Question

In the diagram, m_COE = 55°. If m2 = 2x and mz3 = x+10, what is the measure of angle 2?

45
30
15
60​

Answer 1

30

Explanation:

You set up the equation, 2x + x + 10=55 and then combine the 3x + 10=55. Minus 10 to both side and that gives you 3x = 45 and divide 3x to 45 and then x = 15 and plug x in 2x(Measure 2) and that equals 30
