The base of an isosceles triangle is 3 feet more than the two equal sides of the triangle. If the perimeter is 27 feet, find the three sides of the triangle.

Question

anonymous · Answer

perimitier of an isosceles triangle is 2x+y|dw:1349035654136:dw|

anonymous · Answer

y=x+3. so then you can plug in the equation as a function of x.
2x+x+3   (since x+3 is y)
therefore, 2x+x+3 or 3x+3=27
3x=24
x=8.
so your equal sides are 8 and your base is 8+3 or 11.

make sense?

anonymous · Answer

yeah but how did you get 27?

anonymous · Answer

??

anonymous · Answer

the perimeter given was 27. so you would set the perimeter equation as equal to 27 to find your exact answers
