Me with these two

1.what is the volume of below composite figure?

2.what is the value of x?

  2. area = 504 cm^2

  3. x = 30°

Step-by-step explanation:

2. The figure can be divided across the middle into a rectangular bottom part and a triangular top part. The triangle will have a base length of 21 cm and a height of 32 -16 = 16 cm. Its area is ...

  triangle area = (1/2)bh = (1/2)(21 cm)(16 cm) = 168 cm^2

The area of the rectangle is the product of its base (21 cm) and height (16 cm). Its area is ...

  rectangle area = bh = (21 cm)(16 cm) = 336 cm^2

Then the total area of the figure is the sum of the areas of its parts:

  total area = triangle area + rectangle area

  = (168 cm^2) + (336 cm^2) = 504 cm^2

A plane figure has no volume. The volume is zero.

3. The angle whose measure is 4x is supplementary to the angle marked 60°, so is 180° -60° = 120°. That means ...

  4x = 120°

  x = 120°/4 = 30° . . . .  divide by the coefficient of x

The value of x is 30°.

i think this could be a possible answer (1 / 84) -1

good luck! : d

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
