Question

In the given figure ∆BAD and ∆ADC are two isosceles triangles,if ∠ABD=64,FIND ∠DAC

Answer 1

Answer:

But in the figure nothing is marked except the angle and the angle doesn't match the question. It will be of great help if you mark the image .

Answer 2

Answer:

42°

Step-by-step explanation:

If l ║ m , then third angle in Δ is vertical to consecutive interior angle to 82° angle and measure of that angle is 180° - 82° = 98° ⇒

x = 180° - (40° + 98°) = 42°

P.S. There is not enough information to solve the problem with ΔBAD and ΔADC. If they are isosceles, then what sides are congruent?
