Answer:
8
Step-by-step explanation:
Answer:
E
Step-by-step explanation:
Using the cosine and sine ratios in the right triangle and the exact values
cos60° =
, sin60° =
, then
cos60° =
=
=
( cross- multiply )
2s = 10 ( divide both sides by 2 )
s = 5
------------------------------
sin60° =
=
=
( cross- multiply )
2q = 10
( divide both sides by 2 )
q = 5
