Answer and Explanation
Your Answer is
Correct Answer is F
Explanation
Because ∠B is 40° and ∠D is 90°, so ∠DAB is 50°. So ∠BAC is 25°. So ∠ACB is 180°-25°-40°=115°.
44. In △ABD below, points D, C, and B are collinear, AD is perpendicular to DB, and AC bisects ∠DAB. If the measure of ∠CBA is 40°, what is the measure of ∠ACB ?
