Question

Find the value of x.

Answer 1

Since an angle and a side have been given, we use the formula on the diagram

Answer 2

Hello!

As we are looking for the opposite side and hypotenuse, we will use the sine.

sin30=1/2

This gives us the equation below.

1/2= 5/x

1/2x=5

x=10

Therefore, x=10.

I hope this helps!
