Isosceles triangles whise sides will exceed their base by 5 inches. if the perimeter is 100 inches, what are thw lengths of the three sides?

Isocolees means that 2 sides are equalegnth

side+side+base=perimiter=100
side is 5 more than base
s=5+b
s+s+b=100
5+b+5+b+b=100
3b+10=100
minus 10 from both sides
3b=90
divide both sides by 3
b=30
s=5+b
s=5+30
s=35

the legnsh are
35in ,35in ,30in
