Step-by-step explanation:
Calculate the slopes between pairs of the 3 points using the slope formula
m =
with (x₁, y₁ ) = (- 9, 3) and (x₂, y₂ ) = (- 3, 9)
m = =
=
= 1
Repeat with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (- 3, 9)
m = =
= - 1
If lines are perpendicular then the product of their slopes = - 1 , then
1 × - 1 = -1
Thus there is a right angle between the 2 lines
Then triangle is right- angled
The largest possible complete design that can be painted on a 24’ x 16’ wall is 252' by 189'
<h3>Scale drawing</h3>Scale drawing involves drawing a drawing in a different size and dimension that is proportional to the original dimension
<h3>Dimensions</h3>The dimensions of the design for the farm scene painting is given as:
The dimensions of the wall is given as:
Convert feet to inches
Divide the dimensions of the wall by the painting to get the scale ratios (k)
Also, we have:
Remove decimal (do not approximate)
By comparison;
21 is less than 24
Multiply 21 by the dimensions of the painting
So, we have:
Hence, the largest possible complete design that can be painted on a 24’ x 16’ wall is 252' by 189'
