Question

Please help ASAP!!!!!

Answer 1

16km

Explanation:

Since its a right angle triangle we can use the pythogorean theorem, which is a^2 + b^2 = c^2

So if we apply it to this situation we get,

12^2 + b^2 = 20^2

144 + b^2 = 400

b^2= 400 - 144

b^2= 256

b= 16

So the answer is 16km

Hope this helped :)
