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
