Question

What is the value of x
A)8
B)6
C)1
D)7

Answer 1

Answer:

D) 7

Step-by-step explanation:

Tangents from the same external point are equal in length.

• 8x - 7 = 6x + 7

Add 7 on both sides.

• 8x - 7 + 7 = 6x + 7 + 7
• 8x = 6x + 14

Subtract 6x from both sides.

• 8x - 6x = 6x + 14 - 6x
• 2x = 14
• x = 7

The correct option is D.
