Answer:
60°
Step-by-step explanation:
This polygon is made out of 6 equilateral triangles.
Angle 3 is part of 1/2 of an equilateral triangle.
Which means that this triangle has angle measures of 30, 60, and 90.
Since there is already a 90 degree angle (right angle) and angle 3 is larger than angle 2.....
Angle 3 = 60 degrees!
