Answer:

see explanation

Step-by-step explanation:

Using the sine and cosine ratios in the right triangle

sin30° = \frac{opposite}{hypotenuse} = \frac{6}{y}

Multiply both sides by y

y × sin30° = 6 ( divide both sides by sin30° )

y = \frac{6}{sin30} = \frac{6}{\frac{1}{2} } = 12

---------------------------------------------------------------------------------------

cos30° = \frac{adjacent}{hypotenuse} = \frac{x}{y}

Multiply both sides by y ( y = 12 )

12 × cos30° = x

x = 12 × \frac{\sqrt{3} }{2} = 6\sqrt{3}

Answer: 5,000cm³
Well, 1 mL (milliliter) is equivalent to 1 cubic centimeter (cm³). There is 1,000 mL in a liter, so there are 5,000 mL in 5 liters and therefore 5 liters equals 5,000 cm³.

A training field is designed by joining a rectangle and two semicircles, as shown below. The rectangle is
crimeas [40]
You know that the rectangle is 94m so we multiply that by 2 and get 188. We would use 70m as the diameter of the circle. multiply the diameter by pi which is 219.91. Then you add 188 to 219.91 and you get you answer.

Find the area of the trapezoid. Leave your answer in simplest radical form.
sveticcg [70]

Answer:

64√3 ft²

Step-by-step explanation:

The short leg of the triangle has length (8 ft)(cos 60°), or (8 ft)(1/2), or 4 ft.

The long leg (represented by the dashed line) is (8 ft)(sin 60°), or

(8 ft)(√3/2), or 4√3.  This is also the width of the horizontal trapezoid.

The area of this horizontal trapezoid is:

      (sum of horizontal sides)

A = ------------------------------------- * (width)

                         2

Here, the area is:

      (18 ft + (18 ft - 4 ft)

= ------------------------------------- * (4√3)

                   2

    32 ft

= ----------- * 4√3  =  64√3 ft²
