Lines AB and CD (if shown) are straight lines. Find x. Give reasons to justify your solutions. PLS HELP! WILL GIVE BRAINLIEST!!

Step-by-step explanation:

m∠DOB = m∠DOE + m∠BOE

m∠DBO = 90 + x

m∠DOB = m∠AOC                    {Vertically opposite angles}

110 = 90 +x

x = 110 - 90 = 20

4x and 6y

im not sure though
