7.3

25.2

Answer 1

25.2

Explanation:

This is an intersection of a tangent and a secant.

Answer 2

25.2

Explanation:

Secant-Tangent Formula:

(whole secant) x (external part) = (tangent)^2

(41+12) * 12 = x^2

( 53) * 12 = x^2

636= x^2

Taking the square root of each side

sqrt(636) = x

25.2=x
