Let x be the time it takes Elias and Niko to polish the silver working together. If Elias works alone, he could polish all the silver himself in 40 minutes. Then, in 1 minute, he will make of the total work. If the same analysis is applied Niko, in 1 minute, will make
of the total work.
Working together Elias and Niko will need x minutes to make all the work. Then, in 1 minute, they will make of the total work. So, the fraction of the total work they make in 1 minute is given by this equation:

As in ΔDAB is a right triangle
Apply pythagorean theorem
Hypotenuse ² = Perpendicular ² + Base²
DB² = AB² + AD²
AB = 5 units
AD = 6 units
Put in the above formula
DB² = 5² + 6²
= 25 + 36
= 61
= 7.8 units (approx)
Now in ΔDCB is a right triangle .
By using the trignometric identity .
As DC = 4 units
DB = 7.8 units (approx)
Put all the values in the trignometric identity .
∠p = 59.15 ° (approx)
Answer:
Volume of the right pyramid = 288 m²
Step-by-step explanation:
Volume of the pyramid =
From the ΔAOB,
By Pythagoras theorem,
AB² = AO² + OB²
(6√2)² = AO² + (6)²
72 = AO² + 36
AO = √(36) = 6 m
Since base of the pyramid is a square so area of the base = (Length × Width) = (side)²
Now volume of the pyramid =
=
= 288 m²
Therefore, volume of the right pyramid is 288 m².
