Okay so the equation you need to use is (x2/a2)+(y2/b2)-(z2/c2)=1
So an equation describing the shape of the tower
in the coordinates where the origin is at the center of the narrowest part of
the tower would be:
<span>x^2 / 100^2 + y^2 /
100^2 – z^2 / 2 * 100^2 = 1</span>
I am hoping that this answer has
satisfied your query and it will be able to help you in your endeavor, and if
you would like, feel free to ask another question.
Answer:
Step-by-step explanation:
recall law of Sines Sin(A) /a = Sin(B) / b
for this question
F = A = 105 and a = 37
E = B and b = 28
then plug those into our law of Sines equations
Sin(105) / 37 = Sin(B) / 28
0.025846 = Sin(B) / 28
28 * 0.025846 = Sin(B)
0.72369 = Sin(B)
arcSin(0.72369) = arcSin ( Sin ( B ) )
46.3599 = B
E = 46° ( rounded to the nearest degree)
Area of a rectangle is the product of length times width. Thus, here we need the product of 8 1/2 inches by 11 inches.
One way of doing this follows: 8.5
8.5
----------
93.5 square inches
Rounding up, this comes out to 94 square inches.
Alternatively: 17 187
---- * 11 = ------- = 93.5 square inches; rounded, that's 94.
2 2
90-n=3n
90=4n
22.5=n
Final answer 22.5
