Scilla [17]

Answer: Assuming the riders starts at the position (20, 0) on the x-axis, the exact position of the rider will be (20cos75, 20sin75) or about (5.18, 19.32).

The angle for 5pi/12 radians is 75 degrees. Therefore, to find the position we can use the sine and cosine of 75 to find the x and y value of the coordinate.

For the y-value, we can write and solve:
sin75 = x/20

For the x-value, we can write and solve:
cos75 = x/20

Answer:

(Triangular pyramid)

Lateral area = 1650 $m^{2}$

Total surface area = 1860.1 $m^{2}$

(Triangular prism)

Volume = 660 $cm^{3}$

Step-by-step explanation:

For the triangular pyramid

Area of triangle = $\frac{1}{2}$ × base × height

Area of the base = $\frac{1}{2}$ × 22 × 19.1 = 210.1

Area of the sides = $\frac{1}{2}$ × 22 × 50 = 550

Number of sides (excluding base) = 3

∴ Total Area = 210.1 + (550 × 3)

= 210.1 + 1650 = 1860.1 $m^{2}$

Lateral Area = (550 × 3) = 1650 $m^{2}$

For the triangular prism

Area of the triangle = $\frac{1}{2}$ × 12 × 5 = 30

Volume = Area x Height

Volume = 30 × 22 = 660 $cm^{3}$
