you don't have enough information.
Your equation assumes that angle a and d are equal.
Where did it state that?
How are the 4 angles related?
Are they the angles of a quadrilateral??
???

There are four angles, a,b,c,d. The measure of angle a is (3x+10) degrees. The measure of angle d is (x+10).What is the value of x?
I made an equation 3x+10=x+10. I think the value is 0.

is there a geometrical figure?
What do you mean by vertical angles?
