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
9/0
0.8 percent
In order to find the answer of .8 which is equivalent to 80%, you would have to do 48 divided by 60.
