Answer:
A=920 ft.
Step-by-step explanation:
Using the formulas
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving for A
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=8·20+17·20+15·20+1
2·﹣84+2·(8·17)2+2·(8·15)2﹣174+2·(17·15)2﹣154=920
-1 is correct answer because
a= -2
b= 5 then
(-2^2-5)^3
(4-5)^3
(-1)^3
-1

PLEASE SEE ATTACHED IMAGE.
The length of an arc, by definition is given by:
s = R * theta
Where,
R: radio
theta: angle of the bow.
We then have to replace:
s = (6) * (135 * (pi / 180))
s = 14.1 in
Answer:
The length of the arc s is:
s = 14.1 in
I will use a quadratic formula:
The rectangle was basically cut into two right angles so all you have to find is the length of the triangle. Using what we know which is the h<span>ypotenuse and the height, use the equation x= the square root of c^2 - a^2.
The base is x = 9.17 in</span>
