Answer:
your right the answer is b
Step-by-step explanation:
Using the Pythagorean theorem:
10^2 = 5^2 +x^2
100 = 25 + x^2
x^2 = 100-25
x^2 = 75
x = √75 = 5√3
-8(x+13)=2(x-7)+4x
-8x-104=2x-14+4x
-8x-104=2x+4x-14
-8x-104=6x-14
Hope this can help.
Circles follow ghe equations
(x-h)^2 + (y-k)^2 =r^2
with center (h,k) and radius r
for this circle it would be
(x-7)^2 + (y-4)^2 = 100
