Answer:
height of the tower = 2358.3 feet
Step-by-step explanation:
To solve this question, we can use the tangent relation of the angle of elevation, where the opposite side of the angle is the height of the tower minus six feet and the adjacent side of the angle is the distance from David to the tower. So, we have that:
tangent(78) = (height - 6)/500
4.7046 = (height - 6) / 500
height - 6 = 2352.3
height = 2358.3 feet
I believe your last coordinate would be (6,3)

andrew=7×£3=£21
Answer:
2/3
Step-by-step explanation:
The slope of a line given two points is
m = (y2-y1)/(x2-x1)
= (4-2)/(0 - -3)
= (4-2)/(0+3)
= 2/3
There are 4! = 24 poosible permutations of the four letters. Let the letters be A, B, C and D. Two permutations will have only letter A in the correct envelope, two more permutations will have only letter B in the correct envelope, two more will have only letter C in the correct envelope and two more will have only letter D in the correct envelope. Therefore 8 out of the 24 possible permutations will have only one letter with the correct address. The required probability is 8/24 = 1/3.
