Y = height
x = distance from tower
tan(19.9) = y/x
tan(21.8) = y/(x-50) ( x is 50 feet closer so subtract 50 from x)
find the tan of the angles:
tan19.9 = 0.362
tan21.8 = 0.400
replace those values in the equations:
0.362 = y /x
0.400 = y / (x-50)
rewrite to solve for height:
0.362x = y
0.400(x-50) = y distribute the 0.400 and rewrite as 0.400x-20 =y
now solve:
0.362x = 0.400x-20
add 20 to each side:
0.362x +20 = 0.400x
subtract 0.362x from each side:
20 = 0.038x
divide both sides by 0.038
x = 20 / 0.038 = 526.3 feet
now that x is known replace x in the original equation and solve for y:
tan19.9 = y /x
0.362 = y / 526.3
y = 0.362 x 526.3
y = 190.5
the height of the tower is 190.5 feet
The line of best fit just reaches the 2000 mark, which on the y axis isn't marked but the most logical choice is 19 gallons.
A - 19 gallons

Answer:
isosceles triangle
Step-by-step explanation:
the shape of cross section is isosceles triangle
Answer:
2/3, 2/3 per minute
Step-by-step explanation:
No. You can't even start. Division by zero is 'undefined', and
the procedure is not even allowed. So it's not correct to even
discuss why it's difficult, or what the answer 'would be'. Math
simply doesn't allow it.
