No.
.. √162 = (√2)*(√81)
.. √81 +√81 = 2√81 = √324
Square root is a non-linear function. sqrt(a +b) ≠ sqrt(a) +sqrt(b)
Step-by-step explanation:
Given that,
The length of a ladder, H = 20 feet
The height of the wall, h = 15 ft
We know that,

h is perpendicular and H is hypotenuse
So,

Now using Pythagoras theoerm,

Hence, the angle made by the ladder and the ground is 48.59° and the ladder is 13.2 feet from the wall on the ground.
The answer is 51 liters.
Since they have a direct relationship, set up a direct proportion.
17/476=x/1428
476x3 is 1428 so
17x3=51
