Add the measurements of the two small angles to find the measurement of the large angle for each problem.

two adjacent angles: 24 and 36 degrees
two adjacent angles: 77 and 80 degrees

two adjacent angles of 56 and 23 degrees


two adjacent angles of 135 and 40 degrees

Angle A = 36°
Angle B = 42°

Angle A + Angle B =   78°  
Angle A = 51 °
Angle B = 27 °

Angle A + Angle B =   78°  
Angle A = 48 °
Angle B = 14 °

Angle A + Angle B =   62°  
Angle A = 94 °
Angle B = 77 °

Angle A + Angle B =   171°  
Angle A = 83 °
Angle B = 32°

Angle A + Angle B =   115°  
Angle A = 24 °
Angle B = 19 °

Angle A + Angle B =   43°

Recognize angle measure as additive. When an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts. Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems, e.g., by using an equation with a symbol for the unknown angle measure.
