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

Answers

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

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

A=\frac{1}{2} bh

where

A is the area

b is the base

h is the height

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

A=\frac{1}{2} bh

20=(\frac{1}{2} )(2x+2)(x)

20=(\frac{1}{2} )2(x+1)(x)

20=x(x+1)

20=x^2+x

x^2+x-20=0

(x-4)(x+5)=0

x=4 or x=-5

Since distance cannot be negative, x=4

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

base = 2x+2

base = 2(4)+2

base = 8+2

base = 10

height = x

height = 4
