Answer:
x = 8, y = 4
Step-by-step explanation:
To find x use the sine ratio in the right triangle and the exact value
sin60° =
, thus
sin60° =
=
=
( cross- multiply )
x ×
= 8
( divide both sides by
)
x = 8
--------------------------------------------------------------
To find y use the tangent ratio in the right triangle and the exact value
tan60° =
, thus
tan60° =
=
=
( multiply both sides by y )
4
= y ×
( divide both sides by
)
y = 4
