Answer:

596.0 ft

Step-by-step explanation:

The relationship between the two legs of a right triangle and an acute angle is ...

Tan = Opposite/Adjacent

The height (h) of the lighthouse is the side opposite the angles of elevation. If d is the distance between A and B, we can write two tangent relations:

tan(14°) = h/770

tan(8°) = h/(770 +d)

Equating expressions for h gives ...

770·tan(14°) = (770 +d)·tan(8°)

770(tan(14°) -tan(8°)) = d·tan(8°) . . . . subtract 770·tan(8°)

d = 770·(tan(14°)/tan(8°) -1) . . . . . divide by the coefficient of d

d ≈ 770·(1.7740609 -1) = 596.03

The distance from point A to point B is about 596.0 feet.

Answer:

Width =9 cm

Length =6 cm

Step-by-step explanation:

Let x be width, then length is x − 3

Let area be E. Then we have: E = x ⋅ (x −3)

54= x^2-3x

x^2-3x-54=0

We then do the Discriminant of the equation:

D=9+216

D=225

X1=3+15 over 2. which is 9

X2= 3-15. over 2. which is -6 Which is declined, since we can't have negative width and length.

Therefore x is 9. So width

So width = x = 9cm and length is x-3 = 9-3cm=6 cm

Felix wants to buy some lemonade for the dinner party.

Xelga [282]

Answer:

Yes. Felix is correct.

Step-by-step explanation:

Find out how much ml does a can of lemonade have, I would assume its 330ml since I searched up the ml of a lemonade can.

Find out how much cans of lemonade there are in 2 packs of 8.

2 packs = 8 x 2 = 16 cans of lemonade

Now find out how much ml 16 lemonade cans equal to.

1 can of lemonade = 330ml

16 cans of lemonade = 330 x 16 = 5280ml

Now let's find 5 bottles of 1 litre.

1 litre x 5 = 5 litres.

5280 = 5 litres and 280ml

So Felix is correct about 2 packs of 8 cans is more than 5 bottles of 1 litre.
