Answer:
x = 4 , y = 2
Step-by-step explanation:
Using the sine / tangent ratios in the right triangle and the exact values
sin60° = and tan60° =
, then
sin60° = =
=
( cross- multiply )
x = 4
( divide both sides by
)
x = 4
and
tan60° = =
=
( multiply both sides by y )
y = 2
( divide both sides by
)
y = 2
