Question

If the distance between the origin and the point P(5, K) is 13 units, the value of 'k' is​

Answer 1

Answer:

Distance between two points (x

1

,y

1

) and (x

2

,y

2

) can be calculated using the formula

(x

2

−x

1

)

2

+(y

2

−y

1

)

Distance between the points (p,−5) and (2,7)=

(2−p)

2

+(7−(−5))

2

=13

⇒

(2−p)

2

+144

=13

(2−p)

2

+144=169

(2−p)

2

=25

2−p=5 or 2−p=−5

p=−3 or p=7
