A company makes steel solids that each have a mass of 1 kg. One of their solids is a square-based pyramid joined to a cuboid as shown below.
The base edges of the pyramid are of length 5 cm, and the height of the cuboid is 4 cm. The density of the steel used by the company is 8g/cm3.
Diagram not drawn to scale
The complete solid has a mass of 1 kg.
Calculate the vertical height of the pyramid.

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

step-by-step explanation:

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
