Answer:
see explanation
Explanation:
Note that
sin60° =
, cos60° =

Using trig. ratios in the right triangle
sin60° =
=
=
( cross- multiply )
2x = 18
( divide both sides by 2)
x =
= 9

-----------------------------------------------------------------------------
cos60° =
=
=
( cross- multiply )
2y = 18 ( divide both sides by 2 )
y = 9
