Question

Find y................

Answer 1

`y = 3`

Explanation:

Given the above right angled triangle, we would use a trigonometric ratio formula to find y.

Given angle = 30°

Hypotenuse = 6

Opposite side = y

Solve for y using the trigonometric ratio formula as follows:

`sin(X) = (opposite)/(hypotenuse)`

`sin(30) = (y)/(6)`

Multiply both sides by 6

`sin(30)*6 = (y)/(6)*6`

`0.5*6 = y`

`3 = y`

`y = 3`
