The correct equation can be used to find the value of x if the shortest side, y, measures 2.1 m is,
⇒ 2.1 + 2x = 7.5
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degree.
Given that;
The isosceles triangle has a perimeter of 7.5 m.
And, the shortest side, y, measures 2.1 m
Now, Let two equal side = x
Hence, We get;
⇒ x + x + y = 7.5
⇒ 2x + 2.1 = 7.5
Thus, The correct equation can be used to find the value of x if the shortest side, y, measures 2.1 m is,
⇒ 2.1 + 2x = 7.5
