Answer:
(15+3d)/6 = c
2 1/2 + 1/2d = c (more simplified)
Step-by-step explanation:
15 = -3(2c +d)
15 = -6c -3d
+3d +3d
15 +3d = -6c
/-6 /-6
(15+3d)/6 = c
2 1/2 + 1/2d = c
The answer is d.6,5
Hope its right.
One of the angles between two non-parallel lines is always less than ; i.e. it is acute. The measure of the acute angle between L1 and L2 is
Start by calculating the point of intersection between and
Make x the subject in
Substitute in
Divide both sides by 5
Recall that:
So, the point of intersection is (3,-5)
Next, calculate the slopes.
L1 passes through (-4,7).
So, the slope (m) is:
Also, we have:
Make y the subject
A linear equation is represented as:
Where:
So, we have:
Because L2 is perpendicular to , the slope of L2 is
So, we have:
<em /><em> --- slope of L1</em>
<em /><em> ----- slope of L2</em>
The angle between them is then calculated as follows:
So, we have:
Take arc tan of both sides
--- Approximately
Hence, the acute angle between L1 and L2 is

Answer:
perimeter of the square painting is 12 meters
Step-by-step explanation:
A square painting has sides that are 3 meters long
the side length of the square is 3 meter. there are 4 sides in a square .
to find perimeter we add all the sides
The perimeter of the square formula is
perimeter of the square painting is 12 meters
