Question

In an isoceles triangle the base is 17 cm less than sum of 2 equal sides if the perimeter of triangle is 75 cm find the length of all three sides

Answer 1

Answer:

23

Step-by-step explanation:

In an isosceles triangle ABC

Given:

AB= AC =x

BC= Sum of side AB and AC-17

BC= x+ x-17 =2x-17

Perimeter=75

To Find

Perimeter= AB+ BC+ AC

75=x+x+(2x-17)

75=4x-17

75+17=4x

92=4x

x=92/4

×=23

Therefore x = 23

AB=AC=x=23

BC=2×23-17

=46-17

=29
