1, yes it is a right angle. 2, yes it is a right angle.3, yes it is a right angle.

Step-by-step explanation:

1.Using the Pythagorean Theorem: 5 * 5 = 25, 12 * 12 = 144, 13 * 13 = 169, so 25 + 144 = 169 so yes it is a right angle.

2. Using the Pythagorean Theorem: 6 * 6 = 36, 8 * 8 = 64, 10 * 10 = 100, so 36 + 64 = 100, so yes it is a right angle.

3. Using the Pythagorean Theorem: 8 * 8 = 64, 15* 15 = 225, 17 * 17 = 289, so 64 + 225 = 289, so yes it is a right angle.

they will manufacture 8496 cars

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
