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
