• w =75, because 45 + 60 = 105 and 180 -105 =75

• w = 105, because 180-(45+60) = 75 and 180 - 75 = 105

• w = 285, because 45+60 = 105 and 105 + 180 = 285

• w= 165, because 180-60 = 120 and 120 + 45 = 165

The value of x should be 75, because the angle shown in the diagram are congruent

• The value of x should be 75, because the angle shown in the diagram are congruent

• The value of x should be 105, because the measure of angles shown in the diagrams add up to be 180

• The value of x should be 140, because the measure of the angle shown in the diagrams should add up to 360 and 360 - (110 +110) = 140

• The value of x should be 70, because the measures of the angles shown in the diagrams
