Answer 1

Answer:

see explanation

Step-by-step explanation:

Since the triangle is isosceles , then the 2 legs are congruent , that is

5n - 17 = 2n + 1 ( subtract 2n from both sides )

3n - 17 = 1 ( add 17 to both sides )

3n = 18 ( divide both sides by 3 )

n = 6

Then

2n + 1 = 2(6) + 1 = 12 + 1 = 13

each of the congruent sides = 13 cm

the third side has length n = 6 cm

Perimeter = 13 + 13 + 6 = 32 cm
