Answer:
The value of a side = 5
Step-by-step explanation:
By using PGT theoram
H² = P² + B²
=> 13² = a² + 12²
=> 13² - 12² = a²
=> 169 -144 = a²
=> 25 = a²
=> √25 = a
=> 5 = a
Answer:
a = 5
Step-by-step explanation:
using Pythagoras' identity in the right triangle.
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
a² + 12² = 13²
a² + 144 = 169 ( subtract 144 from both sides )
a² = 25 ( take square root of both sides )
a = [tex]\sqrt{25}[/tex] = 5

If sin 1/3, what are of the values of cos 0 and tan 0?
Answers
Answer:
B
Step-by-step explanation:
SohCahToa
Sin opposite/hypotenuse
Cos adjacent/hypotenuse
Tan opposite/adjacent
so if sin is 1/3 the opposite is 1 and the hypotenuse is 3
to find cos do a^2+b^2=c^2
1^2 + x^2 = 3^2
1+x^2=9
subtract 1 from both sides
x^2=8
do the square root x=2 sq root 2
that leaves u with
opposite is 1
hypotenuse is 3
adjacent is 2 sq rt 2
cos= 2 sqrt 2 / 3
tan= 1 / 2 sq rt 2 which is also eqal to sq rt 2 / 4

Last year, jess saw x dramas and y comedies at the movie theater. if she went to the theater no more than 8 times, which inequality best represents the number of movies she saw? x y < 8 x y > 8 x y ≤ 8 x y ≥ 8
Answers
Assuming she went to the theater no more than 8 times. The inequality best represents the number of movies she saw is: x + y ≤ 8.
InequalityThe inequality that represent the number of movies is: x + y ≤ 8
Where:
x represent drama at the movie theater
y represnt comedies at the movie theater
≤ represent less than
8=Number of times
Therefore the inequality is: x + y ≤ 8.

The value of angle 2 = 40°
Step-by-step explanation:
Given : angle 1 = 140°
angle 1 + angle 2 = 180° { because they are linear pair }

Let's find the measure of major arc MNB:
360 - arc MB = major arc MNB
Now, let's plug in what we know:
360 - (80 + 60) = major arc MNB
Next, combine like terms, and replace "major arc MNB" with "x."
360 - 140 = x
220 = x
Now, we know that the measure of major arc MNB equals 220 degrees.
Angle MLB is going to be double the measure of major arc MNB, so let's set up an equation for this situation:
2(Angle MLB) = major arc MNB
Now, let's plug in what we know:
2(9x + 2) = 220
Finally, let's solve for x:
18x + 4 = 220
18x = 216
x = 12
