I really need help with this.

Question

Solve for both x and y (Round to the nearest tenth):

Answer 1

Let's figure out x first. We know the opposite and adjacent sides for <x so we need to use tan.

tan(x) = 40/20. So we take the inverse tan of both sides to get x by itself. tan^-1(40/20) = 63.4 degrees.

The acute angles in a right triangle are complementary so y = 90 - x. y = 26.6 degrees.
