Question

What is the measure of angle 1

Answer 1

Answer:

Angle 1 is 75 degrees (c) & Angle 2 is 105 degrees (e)

Sum of 6 & 7 is 180

Step-by-step explanation:

75 degrees is directly across from angle 1, meaning they are the same. These are vertical angles.

Angle 2 & 75 degrees are supplementary angles, meaning they add up to 180 degrees.

Knowing that, we can do 180 - 75 = 105

6 & 7 are also supplementary, meaning that they are equal to 180 (a straight line).

Hope this helped. :)
