sin T = t/v

cos T = u/v

cos U = t/v

sin U = u/v

Step-by-step explanation:

Part 1

The sum of the interior angles of a triangle is 180°

⇒ ∠T + ∠U + ∠F = 180°

⇒ ∠T + ∠U + 90° = 180°

⇒ ∠T + ∠U = 90°

Two angles are complementary when they add up to 90°

Therefore, ∠T and ∠U are complementary angles

Part 2

sin(x) = O/H      cos(x) = A/H      tan(x) = O/A

(where x is the angle, O is the side opposite the angle, A is the side adjacent the angle, H is the hypotenuse)

sin T = t/v

cos T = u/v

tan T = t/u

sin U = u/v

cos U = t/v

tan U = u/t
