Question

Which equation can you use to solve for x?

Answer 1

In the given figure three angles are marked x°, 56° and 146 °

When two lines intersect they form two pairs of opposite angles. Vertical angles are always congruent, which means that they are equal.

In the figure angles x ,56 and 146 are formed on two opposite sides of the straight lines are so are vertically opposite angles and hence they are equal.

We can write this as x+56=146.

The first option is the right answer.

Answer 2

I think it is x+146=180
