Answer:
12
Step-by-step explanation:
First, you will have to use trigonometry. Since the side of the triangleis the opposite of the angle 53 and the hypotenuse, you will use sin.
Sin 53 degrees = opposite side / hypotenuse side.
The opposite side is x and the hypotenuse side equals 15.
sin53= x/15
15 ( sin 53 ) =x
x= 11.97953
Round
x=12
Step-by-step explanation:
(5x+18) - (3x+12)
5x+18=3x+12
5x-3x=2x
18-12=6
2x+6
Using the Pythagorean theorem we can solve for the radius
