If y’all solve them foe me i’ll love u forever

A) Subtract A and C from both sides:

B = 180-A-C

B) Divide both sides by p and t:

r = i /pt

C) Divide both sides by PIh

r^2 = V/pih

Take the square root of both sides:

r = SQRT(V/pih)

D) Subtract ax from both sides:

by = c-ax

Divide both sides by b:

y = (c-ax)/b

mark other person brainliest

the answer is 8/21

hope this
