By looking at the diagram, we see that angle C is 45 degrees, angle A is 90 degrees, and angle B is unknown

Given that the sum of all the triangle's angle is 180 degrees, angle B is also 45 degrees

This means that we have a 45-45-90 triangle, which has some special properties as shown in the diagram I uploaded.

Thus <u>BC in the simplest term is </u>14\sqrt{2}

Hope that helps!

Answer:

He must start his journey by 11 AM

Step-by-step explanation:

Speed of Toshi while walking up the mountains is 1.5 kilometres per hour

Speed of Toshi while walking down  the mountains = 2 * Speed of Toshi while walking up the mountains = 3 kilometres per hour

Time taken to travel 9 Km in the upward direction by Toshi = 9 Km/1.5 kilometres per hour = 6 hours

Time taken to travel 9 Km in the downward direction by Toshi = 9 Km/3 kilometres per hour = 3 hours

He will take total 6 hours + 3 hours = 9 hours to travel 18 Km distance

Thus, He must start his journey by 11 AM
