Question

How do I solve this?

Answer 1

First let's start off with the third angle. What do 3 angles in a triangle ALWAYS add up to?

Answer 2

I know that the three angles always add up to 180, but the question is asking about side lengths.

Answer 3

Yes, but if all three angles are 60, what kind of triangle would it be?

Answer 4

Oh, it would be equalaterel. so then the side lengths would also be the same, right?

Answer 5

so than you know that there are two angles with measure of 60 and 60 so and you wrote above that the sum of angles of a triangle is equal 180 degrees so how many degrees will have the 3rd angle ?

Answer 6

yes you are right is equilateral

Answer 7

Yes, and if the side lengths are the same, then you can set them equal to each other:

Answer 8

so just make equal 2x-3=4 and solve it for x

ok. ?

Answer 9

yes you are right
