if the angles are equal that means $$3x=x+40$$solve for $x$

anonymous · Answer

when you find $x$ multiply it by $4$ to get your answer, or add $40$ to it, the answers must be the same

Satellite has it!

anonymous · Answer

did you solve $$3x=x+40$$yet?

maddy1251 · Answer

@satellite73 Couldn't they look at it such as ;
$$3x = 1x + 40$$

maddy1251 · Answer

If so that may help them solve it.

maddy1251 · Answer
