Answer:
1731 ft
Step-by-step explanation:
The tangent relation is useful in this problem.
Tan = Opposite/Adjacent
The height of the light is found to be ...
tan(11°) = height/(639 ft)
height = (639 ft)·tan(11°) . . . . . solve for height
Then the distance from the light to point B is ...
tan(3°) = height/(B distance)
B distance = height/tan(3°) = (639 ft)·tan(11°)/tan(3°) ≈ 2370 ft
Then the distance from point A to point B is ...
2370 ft -639 ft = 1731 ft . . . AB distance
1 hour and 17 minutes. Subtract the total time with the time spent at his friends (C)
Answer: Jessica wants 120 plants in her garden.
Explanation:
Lets find the area of the triangle first:
Tip: the formula can be base x height divided by 2 so you cant get confised about 1/2bh.
Any side of the triangle can be a base, once u find a base, there will always be one corresponding height.
In this case, the base is 12 feet
And the height is 5 feet because that side is perpendicular/corresponding to the base, meaning that the side connects to the base in a 90 degree angle.
So we have this:
12 x 5/2 = 30
The area of the triangle is 30 square feet.
Now, if Jessica wants 4 plants for each square foot of area, we do this:
4 x 30 = 120
