Supplementary angles are angles that usually share a common side, but they don't have to. If you joined them together, they would measure a straight angle and together they form a straight angle which measures 180°. If the sum of the measures of two angles is 180°, then the angles are classified as supplementary angles.

An example of a supplementary angle is provided in the image attached.

We are given:

Parallelogram CDEF
∠C = 13x - 10
∠D = 5x + 10

To Find: ∠E

Concept Used:

Adjacent angles of a Parallelogram are Supplementary

Finding the value of 'x':

Since adjacent angles of a parallelogram are Supplementary:

∠D + ∠C = 180

5x + 10 + 13x - 10 = 180 [replacing the values of angle C and D]

18x = 180

x = 10 [dividing both sides by 18]

Finding Measure of Angle D:

We are given that:

∠D = 5x + 10

∠D = 5(10) + 10 [since x = 10]

∠D = 60°

__________________________________________________________

Finding the measure of ∠E:

∠D and ∠E are Adjacent angles

Since Adjacent angles are Supplementary:

∠D + ∠E = 180

60 + ∠E = 180

∠E = 120° [subtracting 60 from both sides]

Hence, the measure of ∠E = 120°
