X = 4 6 12 please help & explain

x = 12

Step-by-step explanation:

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

x * 3 = 6^2

3x = 36

Divide by 3

3x/3 = 36/3

x = 12

x = 12

Step-by-step explanation:

Apply the Secant-Tangent theorem.

The product of the length of the secant segment and its external part equals the square of the length of the tangent segment.

(whole secant) × (external part) = (tangent)²

(x) × (3) = (6)²

3x = 6²

3x = 36

(3x)/3 = 36/3

x = 12

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

x equals 1
