Here is your answer

Here,

/_BAC= /_DAE (pair of vertically opposite angles )

so,

x+10=2x-10

=> 2x-x= 10+10

=> x= 20

/_ BAC = x+10= 20+10

so,

/_BAC= 30 degrees

Answer:

BAC = 30

Step-by-step explanation:

BAC and CAE are vertical angles, so they are equal

BAC = CAE

x+10 = 2x-10

Subtract x from each side

x-x+10 = 2x-x-10

10 = x-10

Add 10 to each side

10 +10 = x-10+10

20 = x

We want to find BAC

BAC = x+10

         = 20+10

BAC = 30
