Question

In the given figure AD = AC = BD. The points, B, D
and C are collinear. If angle CAD = 80°, then find
angle DAB​

Answer 1

Answer:

25°

Step-by-step explanation:

as AD and AC are equal their angles are equal

let angle ADC and angle ACD be x° then 2x+80=180

x=50°

the exterior angle is the sum of opposite interior angle and as AD and BD are equal their angles are also equal. let angle DAB and angle ABD be y° then y+y=50°

y=25°

Answer 2

Step-by-step explanation:

y= 25 is the answer
