Equation of line joining the origin and centroid of a triangle having vertices (1, -2), (3, 5) and (5, -6).

Step-by-step explanation:

the formulae for finding centroid is (x1+x2+x3/3 , y1+y2+y3/3)

so the coordinates of centroid is (1+3+5/3 , -2+5-6/3)

(3,-1) and other point is the origin (0,0)

we know ,the equation is

x-x1/x1-x2= y-y1/y1-y2

x-3/3-0= y-(-1)/-1-0

x-3/3=y+1/-1

-x+3=3y+3

or -x+3y=0

or x-3y=0(multiplying -1 in both sides)

so the eq is x-3y=0 ans

thank u

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

i dont understand the question? ?
