Question

In the diagram, m∠COE = 55°. If m∠2 = 2x and m∠3 = x+10, what is the measure of angle 2?

Answer 1

Subtract 55 from 180 total degrees of a triangle to get 125.
Put 2x and x + 10 together...
3x + 10 = 125
Subtract 10 from both sides...
3x = 115
Divide by 3...
x = 38.3333

Now to find the measure of angle 2...
38.333(2) = 76.66666
Don't know if that's a multiple choice question or not, but that's what I got

Answer 2

15

30

45

60

Are the answer choices.

Answer 3

D: I guess I did it wrong then lol

Answer 4

oh ok I got it this time:
so 3x + 10 = 55
Subtract 10 from each side...
3x = 45
Divide by 3...
x = 15
