Answer:
1. 102 ft^2 2. 33 ft^2 3. 112 ft ^2
Step-by-step explanation:
you have to find the area of each section of each shape, then add
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:
We know that
sin²x+cos²x=1
so
clear cos x
cos x=(+/-)√[1-sin²x]
in this problem
<span>Angle 0 is in quadrant 1 -----> cos o and sin o are positive
</span>sin o=2/5
cos x=√[1-(2/5)²]----> cos o=√[1-4/25]----> cos o=√[21/25]---> cos o=√21/5
the answer is
cos o=√21/5
