Question

What is the value of x in the triangle?

Answer 1

Answer:

A

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = $\frac{1}{2}$ , then

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{8}$ = $\frac{1}{2}$ ( cross- multiply )

2x = 8 ( divide both sides by 2 )

x = 4
