Answer:
The distance between house to work is 13 miles .
Step-by-step explanation:
Given as :
The distance that man travel to north = OA = 5 miles
Now, From north ,man turn right and travel to east
So, The distance that man travel to east = AB = 12 miles
Let The distance between house to work = x miles
So, x miles is the displacement from north to east direction
i.e x = ![\sqrt{OA^{2} + AB^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7BOA%5E%7B2%7D%20%2B%20AB%5E%7B2%7D%20%20%7D)
Or, x = ![\sqrt{5^{2} + 14^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B5%5E%7B2%7D%20%2B%2014%5E%7B2%7D%20%20%7D)
Or, x = ![\sqrt{169 }](https://tex.z-dn.net/?f=%5Csqrt%7B169%20%20%7D)
∴ x = 13
So, The distance between house to work = x = 13 miles
Hence, The distance between house to work is 13 miles . Answer
Is a calculator allowed? 8/13 = 0.61538. Then take arccos of that to get 52 degrees. Arccos on a calculator might be seen as acos or inv-cos.
