its an emergency. please help​

Answer 1

Answer:

a) 72°

Step-by-step explanation:

To get angle BAC as 72° , join ED and prove by congruency that ∆ ABE is congruent to ∆DCE. Then let angle BAD = angle DAC= x° and angle ABE = angle EBC = Angle C = y°. Then by using Angle Sum property of ∆ , and making some linear equations and use exterior angle property, prove that x=y and then again use ASP to get angle x= 36°

==> 2x= 72° = angle BAC
