Answer:
x = 10
, y = 10
Step-by-step explanation:
Using the sine/ cosine ratios in the right triangle and the exact values
sin60° =
, cos60° =
, then
sin60° =
=
=
( cross- multiply )
2x = 20
( divide both sides by 2 )
x = 10
and
cos60° =
=
=
( cross- multiply )
2y = 20 ( divide both sides by 2 )
y = 10
Answer:
Step-by-step explanation:
420 = 1/4 so 4/4 is 4 420s
