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.
Ответ:
1,225 = r^2 + 625 + 50r + r^2
1,225 = 2*r^2 + 625 + 50r
2*r^2 + 50r -600
radius = 8.86
