Question

Using the figure below, answer the questions that follow.

1. Name the angle that supplementary to /ABD.
2. If m/ABD = 160, what is m/CBD?
2. Name an angle that is supplementary /CBE.​

Answer 1

Answer:

1. Supplementary angles are the set of 2 or more angles that make the total sum to be 180°

In the given question, ABC is a straight line. Therefore /ABD+/DBC = 180°.

So /DBC is supplementary to /ABD

2. Using the above explanation, /ABD+/DBC = 180°

So, /DBC= 20°

3. Angle supplementary to /CBE is /ABE
