One of the unknown angles (let's called it n) has a complement (meaning their sum adds up to 90 degrees) and the other angle is 8 times the unknown angle (8n)
With all this information, you should have the equation:
n + 8n = 90
To solve, combine like terms to get:
9n = 90
Divide by 9 on both sides to isolate the variable n.
n = 10
Now we plug back in to find our angle measurements. The first angle, n, is 10 degrees. The second angle, 8n, is 8 * 10 which is 80; the second angle is 80 degrees.

Sin 0 sin 3pi/2 and tan pi
cos pi/2 is -.5
cos 0 is 1
Oh, well if it isn’t slope! I used to do this don’t cheat kiddo figure it out
Answer:
9
Step-by-step explanation:
Special right triangle
this is a 45, 45, 90 triangle
Meaning that whatever the hypotenuse is
that it will be the same for x
