Answer:
complementary
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
