Answer:

53+53=106

180-106=74

74 + 53= 127 (answer 1)

53+53=106 (answer 2)

74+53=127 9answer 3)

The measure of each exterior angle is 106, 127, and 127 degrees if the two angles of a triangle measure 53.

In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.

We have:

Two angles of a triangle measure 53:

The measure of the angles of a triangle:

53, 53, (180-53-53)

53, 53, 74 in degrees

As we know,

The sum of the two interior angles of a triangle is equal to the exterior angle:

Exterior angle(1st vertex) = 53 + 53 = 106 degrees

Exterior angle(2nd vertex) = 53 + 74 = 127 degrees

Exterior angle(3rd vertex) = 74 + 53 = 127 degrees

Thus, the measure of each exterior angle is 106, 127, and 127 degrees if the two angles of a triangle measure 53.

Answer:

The slope of the parallel line is 2

Step-by-step explanation:

Parallel lines have equal slopes, so for this question you need to re-format the equation to match a y=mx+b format (slope-intercept form).

2x -y = 7  |  Subtract 2x from both sides

-y = 7 + 2x  |  Multiply by negative one to make y even

y = 7 + 2x  |  Rearrange the equation to match the formula

y = 2x +7  |  2 is your slope for both parallel lines!

Answer:

13

Step-by-step explanation:

AB = 20

DE =12

Since AB and DE bisect each other, therefore:

AC = CB = ½(AB)

AC = CB = ½(20)

AC = CB = 10

Also,

DC = CE = ½(DE)

DC = CE = ½(12)

DC = CE = 6

Since F is the midpoint of DC, therefore:

FC = ½(DC)

FC = ½(6)

FC = 3

Find the value of FC + CB. Plug in the values of FC and CB:

3 + 10 = 13

Answer: 1134

Step-by-step explanation:

Step-by-step explanation:

second one because

only x+2y=8 passes through the point (2,3)

the proof is 2+2*3=2+6=8

if we replace the given point to the other equations we will take wrong results for example

first equation

x+2y=4. 2+2*3=2+6=8 that is not equal to 4

Slopes of lines which are parallel to each other is same. The equation of the line which is parallel to y = mx + c and passes through (2,3) point is y = m(x-2) + 3

Parallel lines have same slope, since slope is like measure of steepness and since parallel lines are of same steepness, thus, are of same slope.

In the line of the form [tex]y = mx + c[/tex], the coefficient of x, which is 'm' here, is the slope of the line [tex]y = mx + c[/tex]

Suppose that the given line be:

[tex]y = mx + c[/tex]

(we assume this, because the question is a bit incomplete as the initial line isn't given)

And we've to find the equation of a line which is parallel to the line given above, and passes through (2,3).

Suppose it be:

[tex]y = mx + b[/tex] (as the slope of parallel lines would be same).

This line passes through (2,3), so the equation must be true for (x,y) = (2,3).

Putting it, we get:

[tex]y = mx + b\\3 = m(2) + b\\3 - 2m = b[/tex]

Thus, the equation of this line is:

[tex]y = mx + b \\y = mx + (3-2m)\\y = m(x-2) + 3[/tex]

Step-by-step explanation:

40 x 0.35 = 14

$14 + $3 = $17

40 ($0.35) + 20 (0.15) = 60 stamps

Answer:

(-13,-1)

Step-by-step explanation:

Moving right means moving positively on the x-axis

Moving left means moving negatively on the x-axis

Follow the equation backwards using the x-coordinate:

Move left 10 units-- -5-10 = -15

Move right 2 units-- -15+2 = -13

Since the y-coordinate did not change, the point you started at is (-13,-1)

Answer:

-32

Step-by-step explanation:

Simply input the x and y values.

New equation:

Step two:

|156|/-4    =-39

Step three:

-39+7      =-32

If you evaluate the expression it comes out to -32

Step-by-step explanation:

The third function has a range of y that is greater than or equal to 0.

A function is a kind of rule that, for one input, gives you one output.

For the first function, it contains negative values for y, so it was eliminated.

The second function did not start from zero, so it was eliminated.

The third function obeys the given condition, but the last function contains negative values for y.

Hence, the third function satisfies the condition that y is greater than or equal to 0.

Let a be the amount of 40% solution and b be the amount of pure alcohol that you will use.

You want to end up with a volume of 660 mL, so

a + b = 660

For each mL of solution used, the 40% solution would contribute 0.4 mL of alcohol, and the pure alcohol will contribute 1 mL of alcohol. In the desired solution, you want a concentration of 80% alcohol, so that it contains 0.8 • 660 mL = 528 mL of alcohol, and

0.4a + b = 528

Solve the system of equations above. Subtracting the second from the first eliminates b and lets us solve for a :

(a + b) - (0.4a + b) = 660 - 528

0.6a = 132

a = 220

Then

220 + b = 660

b = 440

So you will need 220 mL of the 40% solution and 440 mL of pure alcohol.

Answer:

Fatima's points = 46

Zahra's points = 30

Step-by-step explanation:

Let's give names to the unknowns (the number of points each one got)

Fatima's points = y

Zahra's points = x

Now create the equations given by the info they provide:

"Fatima got 16 marks more than Zahra"

y = x + 16

"The product of their mark is 1380."

x * y = 1380

Now use the first equation as substitution for "y" in the second equation:

x * (x + 16) = 1380

reduce the expression:

x^2 + 16 x = 1380

x^2 + 16 x - 1380= 0

Solve using quadratic formula:

[tex]x=\frac{-16+/- \sqrt{16^2+4(1380)} }{2} \\x=\frac{-16+/- \sqrt{5776} }{2} \\x=-8+/- 38\\x = 30\,\,\,or\,\,\,x=-46[/tex]

we pick 30 since the scores from a test must be larger than zero.

Now we use the first equation to solve for the other variable;

y = 30 + 16 = 46

then x = 30 and y = 46

Answer:

If you have both legs, then you can use the PYTHAGOREAN THEOREM to find the value of the hypotenuse. a^2 + b^2 = c^2 ( a= leg, b = leg, c = hypotenuse)

Step-by-step explanation:

If you do not have a leg value, but you do have an angle measure, then you can use Sine or Cosine to find the hypotenuse. Sin = opposite/hypotenuse and Cos = adjacent/hypotenuse.
