The picture shows the answer I got!
Also! For the future, I use a site called
math way and it is great for problems like these.

Answer:
Cosθ= -1/25 ;
cotθ= -1/24 .
Step-by-step explanation:
let's recall that in an isosceles triangle, the twin sides make twin angles at the bottom/base, so on the triangle on the left-side, if the "vertex" atop has an angle of 116°, then the twin sides below are simply 180° - 116 = 64, split that in half and that's 32° each.
The same is true for the isosceles triangle on the right side. Also recall that a flat-line is always 180°, 32 + 72 + 76 = 180.

Answer:
x=24
Step-by-step explanation:
Use Pythagorean Theorem to solve for x.
7^2+x^2=25^2
49+x^2=625
-49 - 49
x^2=576
sqrt sqrt
x=24
