Question

The isosceles triangle has a perimeter of 7.5 m. Which equation can be used to find the value of x if the shortest side, y, measures 2.1 m?

Answer 1

Perimeter of triangle = 7.5+y+x

Answer 2

An isosceles triangle has 2 equal and an unequal side. Total perimeter of triangle is 7.5 m, So the sum of the length of the equal sides are (7.5-2.1) m is 5.4 m. So length is half of 5.4 m that is 2.7m because both sides are equal.... So the value of X is 2.7 m
