A triangle has a perimeter of 50. If 2 of its sides are equal and the third side is 5 more than the equal sides, the length of the third side is _____?
- 20
- 30
- 40
- None of these
Explanation
Let equal sides = xThird side = x + 5
Perimeter = x + x + (x+5) = 50
3x + 5 = 50
3x = 45
x = 15
Third side = x + 5 = 15 + 5 = 20
