Question

Distance of point (x1,y1) from origin

Answer 1

Answer:

$\sqrt{ {x1 }^{2} + {y1}^{2} }$

Step-by-step explanation:

$distance \: formula = \sqrt{ {(x1 + x2)}^{2} + {(y1 + y2)}^{2} }$

NOW WE HAVE TO CALCULATE DISTANCE FROM ORIGIN SO

COORDINATES OF ORIGIN (0,0)

AND GIVEN COORDINATES ARE (X1,Y1)

SO USING DISTANCE FORMULA

$\sqrt{ {(x1 - 0)}^{2} + {(y1 - y2)}^{2} }$

=

$\sqrt{x1 ^{2} + y1 ^{2} }$
