Answer:

140°

Step-by-step explanation:

A. B

D C

Is cyclic quadrilateral

then ,

measure of angle ACD + measure of angle BAD =180. ........( BY theorem of cyclic quadrilateral)

40°+BAD =180°

BAD =180°-40°

BAD =140°

The measurement of BAD=50^{\circ}

Step-by-step explanation:

Angle ACD=40 degrees

AB is a diameter of circle

Angle subtended by half circle at the circumference of  circle is equal to 90 degrees

Therefore, angle ACB=90 degree

Angle BCD=Angle ACB+angle ACD=40+90=130 degrees

We know that in cyclic quadrilateral

Sum of opposite angles of cyclic quadrilateral=180 degrees

By using this property

Angle BAD+angle BCD=180 degrees

Substitute the values

130+\angle BAD=180

\angle BAD=180-130=50

\angle BAD=50^{\circ}
