Question

Find the length of each of the equal side of an isosceles
triangle,if the perimeter and
unequal side are..plz tell by example and tell fast​

Answer 1

Answer:

Just subract the measure of unequal side from the perimeter and divide it by 2

Step-by-step explanation:

The perimeter= sum of all sides

=X+Y+Y

=X+2Y

Y=( perimeter*X ) / 2

Side 1 =X

Side 2 =Y

Side 3 = Y

Eg:-

Perimeter=7 cm

Unequal side=3 cm

2Y=7-3

Y=4/2

Y=2
