-
- using formula
h^2=b^2+l^2
h^2=24^2+18^2
h^2=900
h=30
option d is right - 9 years agoHelpfull: Yes(19) No(0)
- ans-d)towards east= 18 km
towards north=24 km
direction =north east
applying Pythagorean triplet=(3,4,5) = 3*6=18, 4*6=24, 5*6=30)
so distance=30 km - 9 years agoHelpfull: Yes(4) No(0)
- Ans-(d) 30km north east
- 9 years agoHelpfull: Yes(1) No(0)
- Ans Is:30km North East
- 9 years agoHelpfull: Yes(1) No(0)
- 30km north-east
- 9 years agoHelpfull: Yes(1) No(0)
- option d by hypotenuse theorem
- 7 years agoHelpfull: Yes(1) No(0)
- Ans - d 30 km
- 9 years agoHelpfull: Yes(0) No(0)
- 30km NorthEast since by formula AC^2=AB^2+BC^2;
- 9 years agoHelpfull: Yes(0) No(0)
- (18)^2+(24)^2=30km north-east
- 9 years agoHelpfull: Yes(0) No(0)
- by pythgorus triples
a^2+b^2=c^2
18^2+24^2=900
so ans is 30 km - 9 years agoHelpfull: Yes(0) No(0)
- 30km northeast
- 9 years agoHelpfull: Yes(0) No(0)
- ans is a:42km north-east
lady runs in right angle path..apply a*a+b*b=h*h - 9 years agoHelpfull: Yes(0) No(1)
- h^2=b^2+l^2
h^2=24^2+18^2
h^2=900
h=30
ans is 30 km north east - 9 years agoHelpfull: Yes(0) No(0)
- 24^2+18^2=a^2
576+ - 9 years agoHelpfull: Yes(0) No(0)
- ans : b)
42km east - 9 years agoHelpfull: Yes(0) No(2)
- option D is right
- 9 years agoHelpfull: Yes(0) No(0)
- 30
SQRT(24^2+18^2) - 9 years agoHelpfull: Yes(0) No(0)
- 42 km east
- 9 years agoHelpfull: Yes(0) No(0)
- H^2=L^2+B^2
Here L=24 and B=18
so H^2=24^2+18^2
=900
under root 90 is 30
So the answer would be 30. - 9 years agoHelpfull: Yes(0) No(0)
- applying pythagorous theorm
let distance from starting point be X
x^2=18^2+24^2
x=30 - 9 years agoHelpfull: Yes(0) No(0)
- When you observe it carefully we can see the formation of triangle.
so by cuing the formula xpower 2=sqrt(24 square +18 square)
therefore x=30Km north-east - 8 years agoHelpfull: Yes(0) No(0)
- 30 km towards north east
- 8 years agoHelpfull: Yes(0) No(0)
- 18km east then from there she will run 24 kms north(i.e from tip of 18 kms a refference she will move in north it is same as east )
so total is 42 km east
- 8 years agoHelpfull: Yes(0) No(1)
- sqrt(24^2+18^2)=30km north-east
- 7 years agoHelpfull: Yes(0) No(0)
