1. In the figure, m DE=124, and M BC=36. The diagram is not drawn to scale. What is m A? A) 44* B) 62* C) 80* D) 88* please help

Anuta_ua [19.1K]

The relation between arc length and exterior angle is given in the figure.

Now we are given far arc length as DE =124

We are given near arc length as BC = 36

So plugging in the formula to find measure of angle A:

$angle A=\frac{far arc-near arc}{2}$

$angle A=\frac{124-36}{2}$

$angle A=\frac{88}{2}$

Angle A = 44 degrees

Answer : A) 44 degree
