Question

Using the figure below, select the pair(s) of supplementary angles. (HINT** they may be more than 1 correct answer)

Answer 1

B and D

Explanation:

Supplementary angles add upto 180 degress, or a straight line. B and D are the only options for angles that add up to 80 degrees.

First, find ange DBE. Angle DBE is 27 degrees as 90-63=27.

ABE is 90 degrees because line AC is a straight line which means it has an angle of 180 degrees and since DBC is 90 degrees, ABD is 90 degrees.

ABE is 117 degrees and EBC is 63 degrees. 117+63=180 degrees

ABD is 90 degrees and DBC is also 90 degrees. 90+90=180

Answer 2

B, D

Explanation:

Supplementary Angles: Add up to 180 degrees

Angle abe and Angle Ebc add up to 180 degrees

Angle ABD and Angle DBC add up to 180 degrees
