Answer 2

$\huge{\boxed{\boxed{\underline{\rm{\purple{Answer}}}}}}$

X= 28

Step-by-step explanation:

We know that

∠AOC + ∠COD + ∠DOB = 180⁰

3x - 7 + 55 + x + 20 = 180

4x + 68 = 180

4x = 180 - 68

4x =112

x = 112/4

x = 28

Checking

3x - 7 + 55 + x + 20 = 180

3 x 28 - 7 + 55 + 28 + 20 = 180

So, our answer is correct
