Question

SOMEONE PLEASE HELP ME FIND THE ANSWER

Answer 1

Answer: 124 degrees

Step-by-step explanation: There is a 90 degree angle in the top right of the circle. There is a 146 degree angle. Add these two angles.

90 + 146 = 236

These two angles combined are 236 degrees. We are trying to find BC, which is the rest of the circle. There are 360 degrees in a circle. Subtract 360 from 236.

360 - 236 = 124

BC = 124 degrees.

Answer 2

The measure of arc BC = 124°

Explanation:

From the figure we can write,

measure of arc AB + measure of arc BC + measure of arc AC = 360

measure of arc AB = 146°

measure of arc BC = 90°

Therefore measure arc BC = 360 - (146 + 90)

= 360 - 236

= 124°

The measure of arc BC = 124°
