Answer:
Direct.
Step-by-step explanation:
A varies directly as the square of r.
Are you sure you wrote all the correct numbers because it does not work
The formula for direct variation is y = kx<span> where k </span>≠ 0
y = 9/x is an inverse relation
17x + 16x + 12x =180
45x = 180
x = 4
Largest angle = 17*4 = 68 degrees
