Answer: the measure of angle 1 is 55 degrees
Step-by-step explanation:
so you see the outside of 5 is 125 degrees on the right side? So that 125 is equal to the 5 on the other side. So to find measure 1 you need to figure out the measure of the rest of the outside which is the outer angle of measure 1.
So you do
125+125=250
and then,
360-250=110
and since measure of angle 1 starts at the edge of the angle and not the center, you do 110/2 which is 55.
IF THE ANGLE OF MEASURE 1 WAS FROM THE CENTER POINT TO THE END DO NOT DIVIDE BY TWO.
