Identify Trig Ratios

Question

In ΔCDE, the measure of ∠E=90°, DC = 37, ED = 35, and CE = 12. What is the value of the sine of ∠D to the nearest hundredth?

Answer 1

sin is opposite/hypotenuse

CE is opposite ∠D

CD is the hypotenuse, as it is opposite ∠E, which has measure 90°

Then, CE/CD = 12/37 ≈ .32.
