What is the trigonometric ratio for sin C?

Enter your answer, as a simplified fraction.

Answer 1

(9/40)

Explanation:

Sin is Opposite/Adjacent

sin(C) = AB/BC

We can find the value of AB by using the Pythagorean Theorem:

a^2 + b^2 = c^2

(80)^2 + b^2 = (82)^2

b = 18

sin(C) = 18/80 or (9/40)
