I need to solve for X in this problem first this are sides and i don't know how much do sides have to equal. I can't explain much because i don;t want to get you guys confused. The picture is uploaded.
THE RED SPOTS ARE ARCS, (Congruent angles)[ITHINK]
The triangle is iscoseles. Therefore, the two "Legs" are congruent. This means that you can find the value of x by making the 2 legs equal to each other.
4x + 10 = 5x - 25
x = 35
Both of the legs are equal so it doesnt matter what equation you put x back into.
So, 4 x 35 + 10 =140
Then, after that just put the value of x into the base to find the length.
3 x 35 + 5 = 110
So, the sides are 110, 140, 140
And, yes the sides can be any length. Only the angles have to add up to 180.
I know this was already answered but i just posted this to put all of the information into one reply.
Hope this helps!
