Question

Maths help please!!!!!!

Answer 1

Answer:

VW = √2

Step-by-step explanation:

y = x+1

x²+y²+2x+2y+1=0          (x²+2x+1) + (y²+2y+1) = 1

(x+1)² + (y+1)² = 1  : Circle: (x-h)² + (y-k)² = r²     Center (O): (h , k) = (-1 , -1) r = 1

solve for roots: x²+(x+1)²+2x+2(x+1)+1=0

2x² + 6x + 4 = 0          x²+3x+2=0

(x+1)(x+2)=0

x = -1 or x = -2

y = 0 or y = -1

V and W: (-1 , 0) and (-2 , -1)  forms a 90° center angle

√vw = √1²+1² = √2
