Question

What is the measure of abc ?

Answer 1

The measure of abc is D. 63 degrees

Answer 2

Option D 63°

Explanation:

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

So by secants theorem,

`(m(AC)+m(DE))/(2)` = ∠ABC = ∠DBE

=
`(1)/(2)` ( 82 + 44 )

=
`(1)/(2)` ( 126)

= 63

Option D 63° is the answer.
