Which set of three numbers could represent the lengths of the sides of a right triangle? a. 7, 9, 11 b. 8, 15, 17 c. 10, 15, 20 d. 12, 18, 22

The answer is B.

Step-by-step explanation:

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

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
