Answer 1

Answer:

AOC = 130

Step-by-step explanation:

We know AB is a staright line, so angle AOB

should be 180

Given,

AOB = 3x - 10 + 50 + x + 20

180 = 3x + x + 50 + 20 - 10

180 = 4x + 60

120 = 4x

30 = x

Now,

AOC = 3x - 10 + 50

AOC = 3(30) - 10 + 50

AOC = 90 - 10 + 50

AOC = 130

Hope this helps....If yes your welcome...
