Anvisha [2.4K]3 years ago
6 0

The answer is:

B. false

Here's why:

The Ptolemaic model is not accurate and this is because the model is geocentric. This means that this model was developed with the assumption  that the Earth was the center of the universe and the sun and the planets revolved around it. Science has already proven that this is not true.

This model was developed by Claudius Ptolemy.

Choose the option that best answers the question. The hypotenuse of a right triangle is 16 ft longer than the length of the shor
FrozenT [24]

Answer: The hypotenuse is 26 ft.

Step-by-step explanation: Let's call the shorter leg of the triangle x. The hypotenuse would be x + 16 and the other leg is y.

As the area is 120, we know that x.y/2 = 120 (because it's a right triangle).

This way, y = 240/x

we know that in a right triangle, we have a² = b² + c²

(x + 16)² = x² + y²

(x + 16)² = x² + (240/2)²

x² + 32x + 256 = x² + 57600/x²

32x + 256 = 57600/x²

32x³ + 256x² = 57600 (÷ 32)

x³ + 8x² = 1800

x = 10

∴

x + 16 = 26

y = 240/10 = 24
