Question

Yadi window (2,y)or(-4,3) ke beech ki doori 10 hai toh y ka Maan kya hai

Answer 1

distance between two coordinates is given by the formula=whole root (x2-x1)²+(y2-y1)² so 10= whole root( -4-2)²+(3-y)²= root36+9+y²-6y=10=root y²-6y+45= 10 squaring both sides 100= y²-6y+45= y²-6y-55 = 0 using quadratic formula y= -b+-root b²-4ac/2a. y= -(-6)+-root(-6)²-4×1×(-55)/2×1=6+-root 36+220/2=6+-root256/2=6+-16/2 so. y= 6+16/2 =11and y= 6-16/2=-5 so y=11 ,-5
