What is the measure of angle 3 if the measure of
angle 6 is 4x + 10 and the measure of angle 7 is 2x + 40?

Answers

Answer:

Angle 3 = 86.8

Angle 6 = 96.4

Angle 7 = 93.2

Step-by-step explanation:

Given :

angle 6 = 4x + 10

angle 7 = 2x + 40

=> angle 6 + angle 7 = 180° { linear pair }

=> 4x+10 +2x+40 = 180

=> 6x+50 = 180

=> 6x = 180-50

=> 6x = 130

=> x = 130/6

=> x = 21.6

so ,the measure of angle 6 = 4x + 10 = 4(21.6) +10 = 86.4+10 = 96.4

the measure of angle 7 = 2x + 40 = 2(21.6) +40 = 43.2+50 = 93.2

now angle 7 = angle 4 + angle 5

and angle 3 + angle 4 + angle 5 = 180°

so, angle 7 + angle 3 = 180

=> 93.2 + angle 3 = 180

=> angle 3 = 180 - 93.2

=> angle 3 = 86.8

In a certain lottery, 5 numbers between 1 and 13 inclusive are drawn. these are the winning numbers. how many different selections are possible? assume that the order in which the numbers are drawn is not important. a. 1287 c. 371,293 b. 154,440 d. 120

Answers

The order in which the numbers are drawn is not important will be 1287.

What is the combination?

A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order.

When order of selecting things does not matter, then the combination odd n things taking r at a time is given by :-

[tex]nC_r=\dfrac{n!}{r!(n-r)!}[/tex]

Given : The total numbers in lottery = 13

The total numbers to choose to win the lottery =- 5

Then the combination of 13 numbers taken 5 at a time is given by

[tex]13C_r=\dfrac{13!}{5!(13-5)!}=1287[/tex]

Hence the order in which the numbers are drawn is not important will be 1287.

To find the unknown angle in this geometry, you must make use of several facts.

an inscribed angle is half the measure of the arc it interceptsthe sum of arcs of a circle is 360°the measure of a central angle is the same as the measure of the arc it intercepts.

__

The long arc intercepted by the inscribed 130° angle will measure 2×130° = 260°. The sum of arcs of a circle is 360°, so the short arc intercepted by the 130° angle (and by x°) is ...

  x° = 360° -260° = 100°

The measure of angle x is 100°.

Find the x-intercept of a line that has the following equation: 2y=3x−6

Answers

Answer:

2

Step-by-step explanation:

To find the x-intercept of the equation we have to substitute y = 0 in it.

=> 0 = 3x - 6

=> 3x = 6

=> x = 2

Therefore the line will meet x-axis at (2,0) which means it'll have x - intercept of 2 units.

Rotate RST 90 degrees counterclockwise around the origin

Answers

Step-by-step explanation:

Unfortunately, you haven't given the coordinates of RST so I can't tell you exactly what the new points will be, but I can tell you what process to follow.

To find a new point rotated 90 degrees counterclockwise around the origin, simply apply the rule:

(x,y) ----> (-y,x)

You would apply this rule of switching the x and y coordinates and y becomes the opposite(so if it was a positive coordinate, it becomes negative and if it was negative, it becomes positive), to get your new coordinates.

<QVR is = to <RVS  and <RVS is = to <SVT, so all 3 angles are = to each other

For the second problem, the perimeter is 46.

This is because it also follows the same rule as 3:2. If you do this for every side, you find out that the sides are 10, 10, 6, 12, and 8. Add them together to get 46.
