Question

For the figure above: Assume that <ABD has a mesure of 105° ANSWER ASAP WILL GIVE 15 POINTS AND BRAINLIEST

Answer 1

Answer:

<CBD =75 degrees.

Step-by-step explanation:

I'm assuming that you want to know the value of <DBC

When a ray has the fixed end on a line, that ray will cut the line into 2 angles that total 180o.

In simpler language <ABD + <CBD = 180

• <ABD = 105 degrees which is a given,
• 105 + <CBD = 180                      Subtract 105 from both sides.
• 105-105 + <CBD = 180 - 105
• <CBD = 75 Degrees                   Answer

Answer 2

Answer:

DBC = 75

Step-by-step explanation:

ABD  and DBC   are  supplementary angles.  They add to 180 degrees.

ABD + DBC = 180

105 + DBC = 180

Subtract 105 from each side

105-105 + DBC = 180-105

DBC = 75
