The base of triangle is 2x + 2 and the height of the triangle is x. find the measure of the base and the height of the height of the area is 20 ft^2

Length of the base = 10

Length of the height = 4

Step-by-step explanation:

Remember that the area of a triangle is given by the formula

where

is the area

is the base

is the height

We know from our problem that the base of the triangle is 2x + 2, so . We also know that its height is x and its area is 20 ft^2, so and . Let's replace the values in our formula to find :

or

Since distance cannot be negative,

Now we can substitute the value for in the base and height:

base =

base =

base =

base =

height =

height =

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
