Answer:

Step-by-step explanation:
we have

step 1

step 2
Factor the leading coefficient

step 3
Complete the square. Remember to balance the equation by adding the same constants to each side


step 4
Rewrite as perfect squares

We know angle BAD= CBA so we can do:
42+105 + x = 180
x = 180-105-42
x=33
Hope this helps!! :)
