Question

The distance of the point A(5,- 5) from origin is

Answer 1

Answer:

5√2 units

Step-by-step explanation:

d = √(x₂-x₁)²+(y₂-y₁)²

co-ordinates of origin = (0,0)

co-ordinates of point A = (5,-5)

x₂ = -5

x₁ = 0

y₂ = 5

y₁ = 0

d = √(-5-0)² + (5-0)²

  = √(-5)²+(5)²

  = √25+25

  = √50

  = 5 x 2 x 5

  = 5√2 units//

Answer 2

Distance from origin is root of (xsquare + y square )
= Root (25+25)
= Root 50
= 5root 2
