what is sqrt(430^2+380^2)?

Answer 2

Pls ans my questions

Answer 3

245343

Answer 4

First draw the north,south,west,east.
a^2=b^2+c^2
So the north will be b
b=430km
So the east will be c
c=380km
So now let's focus on the hypotenuse
According to Phythagoras Theorem
a^2=b^2+c^2
a^2=430km^2+ 380km^2
a^2=184900km+144400km
a^2=329300
Take the square root of both sides
a=573.846669km
a=573.8km



b=430km
So the east will be va
