First you have to find the angle B (check attachment)
Then you can find the last angle inside the triangle, which I'll call C
Now you can find angle A
You almost had it right! remember the equation of a circle is
(x - h)^2 + (y - k)^2 = r^2. the center is (h,k) and r is the radius.
(x - 0)^2 + (y - 0)^2 = 5^2
x^2 + y^2 = 25 <<< your answer
hope that helps, God bless!

I believe the answer would be 6.96 cm
