Question

Find the value of x and the value of y.

Answer 1

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

Answer 2

C

Explanation:

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

sin30° =
`(opposite)/(hypotenuse)` =
`(y)/(8)`

Multiply both sides by 8 × sin30° = y

⇒ y = 8 ×
`(1)/(2)` = 4 → C
