Answer:
Step-by-step explanation:
Complementary angles are 2 angles when added together = equal 90 * degrees.
The verticle angles theorem states angles opposite each other are the same degree*.
30* degrees is opposite angle 2 .
So angle 2 = 30* too
angle 2 and 3 together +equal 90* degree.
90 - 30 (angle 2) = 60*
Angle 3 is 60*
