Question

Find the value of x and the value of y.

Answer 1

Answer:

C

Step-by-step explanation:

Using the sine ratio on the right triangle on the right side

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{y}{8}$

Multiply both sides by 8 × sin30° = y

⇒ y = 8 × $\frac{1}{2}$ = 4 → C

Answer 2

This would be D cause these are 30,60, 90 angles. 30 (X) 60(X square root of 3 and 90 2x).
