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
/_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
