In the diagram, segments AD and AB are tangent to circle C. Solve for x. A)
x = 3

B)
x = 9

C)
x = 13

D)
x = 3; x = -3

3

Step-by-step explanation:

1. according to the condition ΔACD=ΔACB, then AB=AD.

2. if to re-write AB=AD, then 11=x²+2, ⇒ x=3;-3.

3. the value of the length can not be smaller than '0', then x=3.

the answer A) x=3

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
