Question

The perimeter of an isoscles triangle is 18 cm . If one of the equal side is 23/4 cm long . find the measure of the third side​

Answer 1

Answer:

Step-by-step explanation:

Perimeter = 18 cm

If one of the equal sides = 23 /4

then the other equal side will also be 23/4

Then we will get the sum of its two sides = 46/4

Let the third side be x

Sum of sides = perimeter = 18

23/4 + 23/4 +x = 18

46/4 +x = 18

multiply both sides by 4

46 + 4x = 18 * 4

46 +4x = 72

4x = 72 - 46

4x=  26

x = 26 / 4  cm
