Fh is tangent to circle g at point f. what is the length of the radius, r? __ units

answer:

radius r = 12 units.

step-by-step explanation:

we have been given that fh is tangent to circle g at point f and we are asked to find the length of radius.

since we know that at the point of tangency tangent is perpendicular to radius. we are given that f is our point of tangency so we will solve for our radius r by using pythagorean theorem.

upon combining like terms we will get,

therefore, length of our radius will be 12 units.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
