Question

HElps What is M∠1 =??

Answer 1

M angle 1 = 145

Explanation:

The measurement of angle one is a combination of all the angles present in the triangle. This means that 115+30 is equal to angle 1

Answer 2

m<1 = 145

Explanation:

I'm going to name the unkown angle y for clarification

<1 will be x

y + 115 + 30 = 180

y + 145 = 180

y = 35

x + y = 180

x + 35 = 180

x = 145
