Question

Which equation can be used to solve for x in the following diagram?​

Answer 1

D

Explanation:

The 2 given angles are vertical and therefore congruent, hence

10x + 10 = 110 → D

Answer 2

D. The answer is (10x+10) = 110

Explanation:

The angle of 110 degrees and the angle defined by the expression (10x+10) are congruent due to the geometric theorem of angles opposed by a vertix. " Angles that are opposite from a vertex are congruent.

So, taking this theorem in account we can define the expression

(10x+10) = 110

That is option D ,
