Question

Find the missing side length using the trig. Round your answer to nearest.

A. X=14.6
B.x=12.2
C. X=15.9
D.X=22.6

Answer 1

B

Explanation:

Using the sine ratio in the right triangle

sin40° =
`(opposite)/(hypotenuse)` =
`(x)/(19)`

Multiply both sides by 19

19 × sin40° = x , thus

x ≈ 12.2 → B
