Triangle jkl has vertices at the following coordinates: j(2, 2), k(-1, 3), and l(-2, -1). determine whether or not triangle jkl is a right triangle. show all calculations for full credit.

  not a right triangle

Step-by-step explanation:

A plot lets you see that the slope of CB is 4/1 and the slope of BA is -1/3. The product of these values is not -1, so the triangle is not a right triangle.

A graphing program can measure the angle to verify it is not 90°.

x=3

Step-by-step explanation:

1) 10x+1-1 = 12x-5-1, this becomes a new equation

Equation: 10x = 12x-6

2) 10x-12x = 12x-12x-6, this become a new equation

Equation: -2x = -6

3) Divide both sides by -2: -2x/2 = -6/2

4) Once you simplify, you will get x=3
