If the hypotenuse of a right triangle is 20 cm and one of the legs is 16 cm, how long is the other leg?
siniylev [52]
Because this is a triangle and we know that we can use the Pythagorean Theorem to find the hypotenuse we just plug in the numbers. But because you have the hypotenuse already you will subtract the leg from the hypotenuse.

A^2+B^2=C^
16^2+B^2=20^2
256+B^2=400 subtract 256 from both sides
B^2=144 now take the square root of both sides
B=12

The second leg is 12 cm long. Your answer is B, the second answer.

The area of the pool along with the walkway will be 20 × 16 = 320 square feet.

Area of the pool without the walkway will be 16 × 12 = 192 square feet.

Therefore area of the walkway will be

352 - 216 = 128 square feet.

Lerok [7]

Answer:

58.5mg of the vitamin in a drink

Step-by-step explanation:

We know...

130% of RDA for vitamin x >> RDA for vitamin x = 45mg >> 130% of 45 = ?? mg in a drink.

1. 130% = \frac{130}{100} = 1.3

2. 130% of 45 >> 1.3(45)=58.5

I hope this helps you?!
