Answer:

1 = 37°      2 = 57°

Step-by-step explanation:

  • All the angles in a triangle have the sum of 180°
  • The small box in the corner of the angle represents 90°

To Find Angle 1

  1. Add ----->    90 + 53 = 143
  2. Subtract ----->   180 - 143 = 37

To Find Angle 2

  • In the middle of the two shapes, they come to a point making them vertical angles. This means if one side is 90° the other side is also 90°
  1. Add ----->   90 + 33 =  123
  2. Subtract -----> 180 - 123 = 57
