The figure shows two semicircles with centers g and h. point b is on both semicircles.
ray df touches each circle at one point only, points fand e. if fe = de = 12, how
long is segment fg?

answer: what equations are there

step-by-step explanation:

%40

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
