Question

How would you do this I am confused???

Answer 1

Angle 1 is equal to 37
so, subtract angle 3 from 180 = 53
then, you add 90 + 53 then subtract it from 180
so, 180 - (53 + 90)
      =37

Answer 2

Angle 2 is 180-127=53 degrees

angle G is 90

triangle has a total of 180 degrees, so angle 1 is 180-90-53=37 degrees
