Question

Find the missing side. Round to the nearest tenth.

38°
X
19

A. 12.6
B. 30.9
C. 11.7
D. 13.1

Answer 1

Answer:

C

Step-by-step explanation:

using the sine ratio in the right triangle

sin38° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{19}$ ( multiply both sides by 19 )

19 × sin38° = x , then

x ≈ 11.7 ( to the nearest tenth )
