Question

Find x correct to one decimal place. y = 60

Answer 1

check attachment for triangle

Answer 2

use SOH CAH TOA
sin (angle) = opposite side / hypotenuse
so for left triangle :
sin 60 = y / h
sin 60 = 60 / h
re-arrange the equation to work out h

This will give you the length of one of the sides on the triangle on the right
repeat for 2nd triangle
