What is the arc measure of major arc ABC in degrees?

Answer 1

Answer: 283

Step-by-step explanation:Khan Academy

Answer 2

measure of arc ABC = 283°

Explanation:

First we have to find y

7y - 7 + 4y + 6 +20y - 11 = 360

31y - 12 = 360

31y = 372

y = 12

Since all the angles are central angles and intercepted arcs of those angles have the same measure,

the measure of arc ABC = 4y + 6 + 20y - 11

= 24y - 5

= 24(12) - 5

= 283
