Question

Find the measure of the numbered angle.

Answer 1

1 = 37° 2 = 57°

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
