Answer: 65°
Explanation:
We are given that angle ACB is 40° and angle CAB is 25°.
Since the two triangles are congruent to each other, the angle of CAB is equal to the angle ACD- of which both are 25°
Similarily, angle ACB is equal to angle CAD- 40°
Knowing that angle CAB is 25° and angle CAD is 40°, simply add the two together to compute angle DAB:
25°+40°=65°
Thus, angle DAB is 65°
