1 answer:

7 0

To find the perimeter of the triangle, you will add the lengths of each side.

We know two of the sides are 16.2 cm. We also know that the third side is half this (16.2/2) or 8.1 cm.

16.2 cm + 16.2 cm + 8.1 cm = 40.5 cm

The perimeter of the triangle is 40.5 cm.

Hey user☺☺

Option a is correct

Because the graph has only one solution.

As the graph touches the x-axis at one point that means that it will have only one solution for x. But we know that a quadratic equation has two solutions. So the graph will have two equal solution and therefore the discriminant will be 0.

Hope this will help☺☺
