Answer: CBD = 133°

Explanation:

A simple rule when it comes to supplementary angles is subtract the first angle given(in this case 47°) from 180°(a straight line is always 180°). So, using this, we can solve for angle CBD:

∠CBD = 180° - ∠ABC

∠CBD = 180° - 47°

∠CBD = 133°

Hope that helps.

Answer:

Explanation:

Angles ABC and CBD are complementary angles, which means that their measures add up to 90°.

Since angle ABC is 47°, then angle CBD must be 90° - 47° = 43°.

angle ABC + angle CBD = 90 degree

47 degree + angle CBD = 90 degree

angle CBD = 90 degrees - 47 degrees

angle CBD = 43 degree
