Answer:
x = 10 , y = 10
Step-by-step explanation:
using the sine and cosine ratios in the right triangle and the exact values
cos60° = , sin60° =
, then
cos60° = =
=
( cross- multiply )
2x = 20 ( divide both sides by 2 )
x = 10
and
sin60° = =
=
( cross- multiply )
2y = 20 ×
= 20
( divide both sides by 2 )
y = 10
