If the measure of angle 2 is 37 degrees, what is the measure of angle 7 AND what is the angle relationship?
Angle 7 = 37 degrees AND Alternate Exterior.
500
If the measure of angle 5=98°, then the measures of angles 3 AND 4 are:
Angle 3 = 82 degrees.
Angle 4 = 98 degrees.
500
If the measure of angle 4 = 5x+3 and the measure of angle 6 = 8x-5, then find the measure of angle 4.
First, x = 14.
So angle 4 = 73 degrees.
