Question

Runners in a long distance race start out going 8 kilometers east and then head north for the remainder of the race. The finish line is 10 kilometers from the starting line. How far did the runners travel north?

Answer 1

draw a triangle and use pisagor

Answer 2

sqrt 10^2 - 8^2
sqrt 100 - 64
sqrt 36
6 km

Answer 3

shanks

Answer 4

you should just draw a triangle and use pisagor theorem, if we say a,b,c edges a=8 and then c = 10 and if the degree between a and b = 90 then to pisagor theorem a^2 + b^2 = c ^2 so that 10^2 = 8^2 + b^2 solve this you will have 6 as the answer ^^ good luck to you
