Answer:

19.6 feet

Step-by-step explanation:

We know that

The hypotenuse is 20 feet, and the bottom leg is 4 feet.

We also know that Pythagorean theorem is used when there is one missing side to a triangle.

$a^{2}$ + $b^{2}$ = $c^{2}$

Substitute in a for 4 and c for 20. The hypotenuse is always the variable c.

4^2 + b^2 = 20^2

16 + b^2 = 400

b^2=384

$\sqrt{384}$ = 19.6

Solve the following

kipiarov [429]

Answer:

2000000 bricks

Step-by-step explanation:

The computation of the number of bricks to be used is shown below:

The Volume of brick is

= (15 × 8 × 5)cm^3

= 600 cm^3

And, the Volume of wall is

= (1500 × 1000 × 800)cm^3

= 1200000000 cm^3

Now Bricks needed is

= 1200000000 cm^3 ÷ 600cm^3

= 2000000 bricks
