Question

In the figure, segment AB is the diameter angle CAB=50° What is measure angle CAD​

Answer 1

Answer:

Angle ACD =90° (angle in a semicircle)

join CB

then sum of the angles in triangle ABC=180°

angle CAB+angle ACB+angle ABC =180°

angle CBA= 180°- (50°+90°)

angle CBA = 40°

angle CDA =40° (angle in major segment are equal)
