Find the measure of the numbered angle.

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

Add >    90 + 53 = 143Subtract >   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°Add >   90 + 33 =  123 Subtract > 180 - 123 = 57
