Question

What is the measure of angle BAC?​

Answer 1

BAC = 30

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
