Question

AB and AD are tangent to circle C. Find the length of AB. A. 39 B. 16 C. 3 D. 13

Answer 1

Answer:

B. 16

Step-by-step explanation:

Since AB and AD are tangent to circle C, they equal each other.

2x + 7 = 3x - 9     Make them equal each other

2x + 7 = 3x - 9      Subtract 2x from both sides

7 = x - 9            Add 9 to both sides

16 =  x
