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?

Verified Answer :

An isosceles triangle’s has two equal sides (x) and one shorter side of a different length (y). The perimeter (p) is equal to 2x + y. 2x + 2.1 = 7.5. 2x = 7.5 - 2.1. x = (7.5 - 2.1)/2. x = 2.7.

Answer:

The answer is 2.1+2*x=7.5

Step-by-step explanation:

If the isosceles triangles shortest side measures 2.1m, measurement of one of the other sides with multiplication by 2 need to give the perimeter of the triangle. Therefore, equation that gives the perimeter of the triangle can be written as:

\(y+2*x=7.5\)

We know that y=2.1 then equation will be:

\(2.1+2*x=7.5\)
