Answer and Step-by-step explanation:
Trigonometric Function (These only work for right triangles):
SOH-CAH-TOA
S = Sine = sin
C = Cosine = cos
T = Tangent = tan
O = Opposite (side)
H = Hypotenuse (side)
A = Adjacent (side)
SOH = sin(angle) =

CAH = cos(angle) =

TOA = tan(angle) =

1. sinQ (Q is the angle) =

Use Pythagorean Theorem to find side PQ.

2. cosQ =

3. tanQ =
