Ответ:
r=9
Step-by-step explanation:
We can use the Pythagorean to solve, since this is a right triangle
The leg lengths are r and 12
The hypotenuse is (r+6)
a^2 + b^2 = c^2
r^2 + 12^2 = (r+6)^2
Foiling out the right hand side
(r+6)(r+6_ = r^2+6r+6r+36
r^2 +144 = r^2 +12r+36
Subtracting r^2 from each side
r^2-r^2 +144 = r^2-r^2 +12r+36
144 = 12r+36
Subtract 36 from each side
144-36 = 12r+36-36
108 = 12r
Divide each side by 12
108/12 = 12r/12
9=r
