Question

Can you please help me understand?

Answer 1

1 is 69
2 is 37
3 is 106
4 is 21

Answer 2

Step-by-step explanation:

Angle 1: (I solved this one last) 69 degrees :) . Because Angle 2 is 37 and we know the other existing angle is 74 we can do 74+37 and subtract that from 180.

Angle 2: 37 degrees. Because Angle 2 and the 53 degree angle add up to a right triangle (90 degrees) you can subtract 90-53 and get 37.

Angle 3: 106 degrees. Because the line is a straight line, all angles should add up to 180 degrees, and 180-74=106.

Angle 4: 21 degrees. Because we know that Angle 3 is 106 degrees, we can do (106+53) and then subtract from 180 because all angles in a triangle should equal 180 degrees.
