In the figure to the right, if AC = 15 and BC = 12, what is the radius?
Andrew [12]

Answer:

The radius is 9.0 units

Step-by-step explanation:

we know that

In the right triangle of the figure ABC

Applying the Pythagorean Theorem

AC^2=AB^2+BC^2

190.4

Step-by-step explanation:

Solve the following system:

{2 y - 3 x - 8 = 3 y + 4 x - 1 | (AB=DE)

4 y + 10 x + 3 = -2 y - 17 x + 9 | (BC=EF)

x = -16/5, y = 77/5

DF=AC=-27x+5y+27=190.4

There you go, have a great day
