Answer:
The value of x is 2.7 and the equation used for finding the value of x is 7.5 = 2.1 + 2x.
Step-by-step explanation:
As given
The isosceles triangle has a perimeter of 7.5 m .
if the shortest side, y measures 2.1 m
In the isosceles triangle two sides of the triangle are equal .
Let us assume that the two equal sides each of length x .
Thus
Perimeter = Sum of all sides
Perimeter = x + x + y
7.5 = 2x + 2.1
7.5 - 2.1 = 2x
5.4 = 2x
x = 2.7 m
Therefore the value of x is 2.7 and the equation used for finding the value of x is 7.5 = 2.1 +2x.
