Question

I need help on finding x. I wasn't at school for the lesson and I looked in my textbook as well.. I just don't get it.

Answer 1

Sorry its so messy I'm still trying to get the hang of how to draw on my laptop lol.

Answer 2

are those angles congruent or equal

Answer 3

congruent...

Answer 4

equal = congruent but we refer to them in a figure

Answer 5

That's what I was just thinking.. But I already know that. I just need help on how to solve for x..

Answer 6

well find the value of x*

Answer 7

ok, here it goes since the triangles are congruent to each other that means that their sides are congruent as well, so one side equals to the other side

thus 12 = 2x -10

Answer 8

ok and then after that I'd subtract 12 from 10.. correct?

Answer 9

in order to solve it you need to add 10 to both sides

Answer 10

oh okay lol so the answer would be x= 11 ?

Answer 11

yes
