Question

What is the measure of angle ACD?
o 117°
o 97°
o 122°
o 167°

Answer 1

117

Explanation:

180-90-27=63 (angle ACB)

straight line=180-63=117

Answer 2

The sum of the interior angles of the triangle is 180°, we calculate
180-(90+27)=63
From this calculation, we know that the angle of the acute of C is 63 °.
The final angle we want to find is the exterior angle of C, so we know that
180-63=117.

Therefore the angle of ACD is 117 °.
