Dwayne’s garden is triangle-shaped with two equal sides and a third side that is 4 ft more than the length of an equal side. if the perimeter is 49 ft, how long is the longest side? type a numerical answer in the space provided. do not type spaces in your answer.

Length of the longest side = 19 feet

Step-by-step explanation:

We know that, two out of three sides of a triangle are equal and the third side is 4 feet more than the length of an equal side. Perimeter of the triangle is 49 feet.

Assuming the length of the two equal sides to be x, the length of the third side will be 4+x.

Perimeter of triangle = a + b + c

So substituting the values of the perimeter and the sides to get"

If x = 15 feet then the longest side = 15 + 4 = 19 feet.

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.
