Answer:
the answer is 59
Explanation:
a circle is 360 degrees, which means half of a circle is 180. This means the angles that are along ray q must add up to 180. if you add the 2 known angles
60+61
you can subtract that from 180
180 - (60+61)= measure angle 4
180 - 121 = measure angle 4
180 - 121 = 59
