Question

One angle is equal to three times its supplement. the measure of the angle is . a)130 o b)135 o c)90 o d)120 o

Answer 1

"c) 90 Degree is the answer.

x+3x = 180

4x = 180

X = 180/4

X = 45 degrees for the smaller angle.

180 – 45 = 135 degrees for the larger angle.

Proof:

45+3*45 = 180

45+135 = 180

180/2 = 90

One angle is 3 times its supplement increased by 68 degrees.

Find the measure of the two supplementary angles.

Answer 2

Answer:

x+3x = 180

4x = 180

X = 180/4

X = 45 degrees for the smaller angle.

180 – 45 = 135 degrees for the larger angle.

Proof:

45+3*45 = 180

45+135 = 180

180/2 = 90

One angle is 3 times its supplement increased by 68 degrees.

Find the measure of the two supplementary angles.
