Question

Perimeter of isoceles triangle is 43cmthe congurent side is 1cm less than twice the lenght of base.find the leanght of each side os a triangle

Answer 1

Answer:

Sides are 9 cm, 17 cm and 17 cm

Explanation:

p = 43 cm

Let base be x

Equal side = 2x - 1

2x - 1 + x +2x - 1 = 43

5x - 2 = 43

5x = 43 + 2

5x = 45

x = 9 cm

Base = x = 9 cm

Equal side = 2x - 1 = 17 cm
