Sagot :

The measure of the angle ∠ABC is 110° and the measure of the reflex angle ∠CBD is 70°.

What is an angle?

Angle is the space between the line or the surface that meets.  And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.

The measure of the angle ABC will be

∠ABC = 110°

The angle ∠ABC and ∠CBD are the linear angles. Then we have

∠ABC + ∠CBD = 180°

   110° + ∠CBD = 180°

             ∠CBD = 70°
