Question

Can someone explain by steps on how to do this

Answer 1

8
`√(3)`

Explanation:

This is a special right triangle with angle measures 90-60-30 degrees

The side lengths are like the following :

The side length that sees 90 degrees is represented with x

The side length that sees 60 degrees is represented with x
`√(3)`

The side length that sees 30 degrees is represented with 2x

the side that sees 90 degrees is given as 16 so x = 8 and so a = 8
`√(3)`
