Question

What is the measure of abc ?

Answer 1

The measure of abc is D. 63 degrees

Answer 2

Answer:

Option D 63°

Step-by-step explanation:

Two secants AE and CD intersect each other at point B inside the circle.

So by secants theorem,

$\frac{m(AC)+m(DE)}{2}$ = ∠ABC = ∠DBE

= $\frac{1}{2}$ ( 82 + 44 )

= $\frac{1}{2}$ ( 126)

= 63

Option D 63° is the answer.
