Question

Select the expression that shows the angle measure 175° decomposed into smaller angles.

65° + 45° + 45°
55° + 55° + 60°
40° + 45° + 45° + 45°
35° + 35° + 35° + 60

Answer 1

40° + 45° + 45° + 45°

Explanation:

Add all the degrees in each expression and figure out which one equals 175°.

65° + 45° + 45° = 155°

55° + 55° + 60° = 170°

40° + 45° + 45° + 45° = 175°

35° + 35° + 35° + 60 = 165°

The third expression (40° + 45° + 45° + 45°) is the only expression that equals 175°.
