![403.2 \: miles](https://tex.z-dn.net/?f=%20403.2%20%5C%3A%20miles)
EXPLANATION
The total length of the trip to and from work is
![19.2 \: miles](https://tex.z-dn.net/?f=19.2%20%5C%3A%20miles)
If Jonah worked 21 days in August,
Then, the total length of the trip to and from work is
![= 21 \times 19.2 \: miles](https://tex.z-dn.net/?f=%20%3D%2021%20%5Ctimes%2019.2%20%5C%3A%20miles)
Change the decimal to fraction and multiply,
![= 21 \times \frac{192}{10} miles](https://tex.z-dn.net/?f=%20%3D%2021%20%5Ctimes%20%5Cfrac%7B192%7D%7B10%7D%20miles)
![= \frac{21 \times 192}{10}](https://tex.z-dn.net/?f=%20%3D%20%5Cfrac%7B21%20%5Ctimes%20192%7D%7B10%7D%20)
![= \frac{4032}{10} miles](https://tex.z-dn.net/?f=%20%3D%20%5Cfrac%7B4032%7D%7B10%7D%20miles)

Answer:
h = 55
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
the 2 unknown interior angles = 180 - 2h ( straight angle ), hence
the sum of the 3 angles
180- 2h + 180 - 2h + 40 = 180
400 - 4h = 180 ( subtract 400 from both sides )
- 4h = - 220 ( divide both sides by - 4 )
h = 55
