Answer:
The answer is x=-5 and y= -8
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
Using the sine and cosine ratios in the right triangle
sin30° =
= 
Multiply both sides by y
y × sin30° = 6 ( divide both sides by sin30° )
y =
=
= 12
---------------------------------------------------------------------------------------
cos30° =
= 
Multiply both sides by y ( y = 12 )
12 × cos30° = x
x = 12 ×
= 6
You have to pay the 90$ we all ready know it’s over 90. 15% of 90 is just 90x0.15 which is 13.50. So the fee (13.50) plus the cost(90) is 103.50$ total for the raft
