Question

Find the value of x. Round your answer to the nearest tenth of a unit.

Answer 1

Answer:

x ≈ 21.4

Step-by-step explanation:

Using the sine ratio in the right triangle

sin31° = $\frac{opposite}{hypotenuse}$ = $\frac{11}{x}$ ( multiply both sides by x )

x × sin31° = 11 ( divide both sides by sin31° )

x = $\frac{11}{sin31}$ ≈ 21.4 ( to the nearest tenth )

Answer 2

Answer:

Sin31°= 11/x

x = 11/Sin31

x= 21.4. ( Nearest tenth).
