Answer:
fourth option
Explanation:
Using the sine and cosine ratios in the right triangle and exact values
sin60° =
, cos60° =
, then
sin60° =
=
=
( cross- multiply )
2x = 4
( divide both sides by 2 )
x = 2
---------------------------------------------------------
cos60° =
=
=
( cross- multiply )
2y = 4
( divide both sides by 2 )
y = 2
