Answer:
Right angle triangle goes to 15m, 8m, 17m
Step-by-step explanation:
Square root of 15^2 + 8^2 is 17
(The use of a^2 + b^2 = c^2 - Pythagoras's Theorem)
So, 10m ,11m ,15m isn't a right angle triangle

i think this answer is helpful for you, isn't it?
8 Kilometers
1m=0.001km
So...
8000m=8km
the possible length for x might be 20
hope this helps :)
