The table gives the surface areas, in square kilometres, of five seas.
zlopas [31]

The table is missing, so i have attached it.

Also, the correct question is;

The surface area of the East China Sea is k times the surface area of the Baltic Sea.

Work out the value of k.

Give your answer to the nearest whole number

Answer:

k = 3

Step-by-step explanation:

From the attached table,

Surface area of east china = 1.25 × 10^(6) km²

Surface area of Baltic sea = 4.22 × 10^(5) km² = 0.422 × 10^(6) km²

We are told that the surface area of East China Sea is k times that of the surface area of the Baltic Sea.

Thus;

1.25 × 10^(6) = k × 0.422 × 10^(6)

k = 1.25/0.422

k = 2.96

Approximating to whole number gives;

k = 3

I don’t understand how to find the height
ANTONII [103]

Answer:

<u>height</u><u>,</u><u> </u><u>x</u><u> </u><u>is</u><u> </u><u>2</u><u>3</u><u>5</u><u> </u><u>ft</u>

Step-by-step explanation:

From trigonometric ratios:

\cos( \theta)  =  \frac{adjacent}{hypotenuse}

but:

\theta = 90 \degree - 36 \degree \\  \theta = 54 \degree

adjacent is x

hypotenuse is 400 ft

\ \cos ( 54 \degree)  =  \frac{x}{400}  \\  \\ x = 400 \ \cos (54 \degree)  \\ x = 235 \: \:  feet
