Answer:
The answer is 3.9
Step-by-step explanation:
Answer:
volume = 720 in³
Step-by-step explanation:
volume = 1/3Bh = 1/3 x 72 x 30 = 720 in³
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

d =√((x_2-x_1)²+(y_2-y_1)²)
This is the formula of distance between
So, I hope u will get all answer of the questions by using this formula...
