Answer:
∠
°
Step-by-step explanation:
- The cosine of an angle is equal to the side adjacent to the angle over the hypotenuse, the longest side.
- We need to find the hypotenuse of this triangle. This is relativly easy to do with a right triangle; we can just use the Pythagorean Theorem.
- Pythagorean Theorem:
where 
, 
, and 
are the 3 different sides of a right triangle.
- Our hypotenuse is
. Now we can finish solving for ∠
.

Given that Pythagorean Theorum is
A^2 + B^2 = C^2, you need to do the opposite.
To find for A^2, you need to:
Subtract B^2 from C^2. This creates the equation of:
C^2 - B^2 = A^2. This works because A^2 + B^2 is C^2, so the opposite must work.
Now if you're looking for A and not A^2, you need to subtract B^2 from C^2 and then square root the difference.
I hope this helps!
