Question

A triangle has a perimeter of 50. If two of the side lengths are equal and the third side is five more than the equal sides, what is the length of the third side?
A. 15
B. 23
C. 20
D. 35

Answer 1

i think its A.

Answer 2

15, 15, 20.
It's C

Answer 3

See, let the two equal sides be x each..
Then the third length will be : x + 5

So, x + x + x + 5 = 50

3x = 45

x = 15 and you can solve it now further..
