Answer:
Angle 1 is 77
Angle 2 is 103
Angle 4 is 103
Explanation:
Angles that are vertical to each other like 2 and 4, 1 and 3
will always equal each other
since 3 is = to 77, 1 is also = to 77
You can also find the angles by thinking of supplementary angles (180 degrees) Straight angle basically
You see that 3 is 77 and 4 is part of the straight line so it needs to equal 180
so 180-77 it will equal 103.
Hope this helps
