OpenStudy (abhisar):

Column A 180-58=122, 122/2=61

OpenStudy (abhisar):

Column B 180-116=64

OpenStudy (anonymous):

There is a special property about the base angles of an isosceles triangle--they are equal. Triangles interior angles add up to 180. @Abhisar summed it up pretty well. Just remember what I said. Now it's all a matter of seeing which one is larger, that would be Column B.

OpenStudy (abhisar):

@AnonymousBeast Thnx for the compliment !

OpenStudy (anonymous):

ok thank you @Abhisar and @AnonymousBeast. do either of yall know the second one

OpenStudy (anonymous):

What is the second one?

OpenStudy (anonymous):

Oh, I see it.

OpenStudy (abhisar):

All sides are equal in an equilateral triangle !

OpenStudy (abhisar):

So just equate the three equations

OpenStudy (anonymous):

You can basically set them equal to each other and solve for one at a time. I would first do: 5x-2=6x-10 ^^^Solve for x. Then, replace x into the following and solve for c. 5x-2=4x+c

OpenStudy (anonymous):

im confused lol

OpenStudy (anonymous):

An equilateral triangle has all 3 sides equal. So, we know for sure that 5x-2=6x-10 since they represent side lengths. That gives us the ability to make them equal to each other. Combine like terms and solve for x. I will do the first for you. 5x-2=6x-10 Add 10 5x+8=6x Subtract 5x 8=x x=8 Now, substitute 8 into the second set I gave you and solve for c.

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

it checked out now what

OpenStudy (anonymous):

What'd you get for c?

OpenStudy (anonymous):

6

OpenStudy (anonymous):

There you go, x=8 c=6. You have your answer.

OpenStudy (anonymous):

thanks
