Angle A and angle B are complementary angles.
The measure of angle A is 40° The measure of angle B is (5x + 10)°.
Which equation can be used to find the value of x?
40 = 2x + 10
40 + (5x + 10) = 360
40 + (5x + 10) = 180
40 + (5x + 10) = 90

Angle B and angle C are supplementary angles.
The measure of angle B is 108° The measure of angle C is (4x + 2)°.
Which equation can be used to find the value of x?
108 + (4x + 2) = 90
108 + (4x + 2) = 180
108 + (4x + 2) = 360
108 = 4x + 2
Answer explanation
supplementary angles form a straight angle = 180º
