Find the value of x. If necessary, round the value to the nearest tenth.

FG is perpendicular to OP, RS is perpendicular to OQ, FG=27, RS=26 OP=16

The answer is 16.4

But how?
~Thank you!

Answer 2

we know a and h, so we know r, we know r and m, so we know b

Answer 3

r = sqrt(a^2 + h^2)

b = sqrt(r^2 - m^2)

b = sqrt(a^2 + h^2 - m^2)
