150 degrees.

Angle A=x
Angle B=5x
x +5x=180 or 6x=180 so x=30. Angle A=30 and angle B=150.

Both angles must equal 180
5x+x=180, add all variables i.e
5x+x=6x=180 divide bothe sides by 6 you have
6x/6=180/6= x= 30
so angle E=30 and angle D= 180-30 = 150

If angles are supplementary then the measures of the angles equals 180...
D = 5E
D + E = 180
(5E) + E = 180
6E = 180
E = 30, therefore D = 150

Suplementary angles add up to 180 degrees, therefore:
E + D = 180
if D = 5E
E + 5E = 6E = 180
E=30
Therefore D=5E = 5 x 30 = 150
Answer D is a 150 degree angle

Supplementary means that their sum is 180 degrees.
The problem you have to solve is: an angle (E), and another angle five times as big (D), are supplementary:
x + 5x = 180
6x = 180
x = 30
E = 30, D = 150
