Question

In given figure the measure of $\angle ACD$ is

• A. ${125}^{\circ }$
• B. ${120}^{\circ }$
• C. ${105}^{\circ }$
• D. ${115}^{\circ }$

Answer 1

The correct option is D ${115}^{\circ }$

We know that angle on a straight line is 180 degree.

$\angle C$ on line BD will be 180 degree.

$\angle ACB+\angle ACD=180$

$\Rightarrow 65+\angle ACD=180$

$\therefore \angle ACD=180-65={115}^0$
