To solve this problem you must apply the proccedure shown below:
1- You have that the equation of the line is:
Where is the slope and
is the y-intercept.
2- Based on the information given in the problem, the lines and
are parallel, which means that both have the same slope. Therefore, you can calculate the slope of
:
3- Use the coordinates of the point to calculate the y-intercept:
4. Solve for :
5. The equation of the line is:
The answer is:
Let us assume base of the window = b feet.
Height is 3 feet less than base, that is = (b-3).
Given area of the triangle = 20 feet square.
We know formula for area of a triangle:
Area = × Base × Height
Plugging values in formula, we get
20 =
Factoring quadratic, we get
=0
b+5=0
b=-5
b-8=0
b=8.
For base we can take only positive value.
<h3>Therefore, base of the triangle = 8 feet and height = 8 -3 = 5 feet.</h3>Answer:
