nope. b^2 = c^2 - a^2
the angles are ok, since you didn't have to use b.
use trigonometric ratios and the Pythagorean theorem to solve the triangle.

c = 13.6 ft
a = 7.2 ft
my answer:
a^2 + b^2 =c^2
7.2^2 +13.6^2 = b^2
51.84 + 184.96 = b^2
√(236.8)= b
15.39 = b
Sin A = 7.2/13.6
A=31.96 = 32
Angle b = 90-32
b= 58
c = 90
is my answer correct?

I had given you the steps, why did you change the equation?
