Step-by-step explanation:
To find x use the sine ratio in the right triangle and the exact value
sin60° = , then
sin60° = =
=
( cross- multiply )
x = 28
( divide both sides by
)
x = 28

To find y use the tangent ratio in the right triangle and the exact value
tan60° = , then
tan60° = =
=
( multiply both sides by y )
14 = y
