Answer: the answer is 19.4m
Step-by-step explanation:
We will usePythagorean theorem
a^2+b^2=C^2
Lets substitute and solve
2^2+b^2=3^2
4+b^2=9 lets subtract 4
b^2=5
b=√5 or 2.2360679775
X=4 so your problem now would be 3+4=7
Hope this helps!
So in short your answer is 4
I calculated with my teacher and somehow we could onu get 667.22
X=2.5
subtract 5 from both sides and then divide 5 by 2.
