Question

find the distance of the point P (3,5) from the origin

Answer 1

By using distance formula,

Coordinates of origin = ( 0,0 )

x 1 = 3, x 2 = 0, y 1 = 5, y 2 = 0

Distance formula = √ ( x2 - x1 ) ²+ ( y2 - y1 ) ²

D = √ ( 0 - 3 ) ²+ ( 0 - 5 ) ²

D = √ 9 + 25

⏺️D = √ 34.

Answer 2

origin (0,0)
OP²= x1²-x2² + y1²-y2² ( using distance formula and squaring both LHS and RHS)
(0-3)²+ (5-0)²
= 9+25
= 34
OP = √34

hope it helped you....
