Answer 1

Answer:

formula of centroid is

X = x1 + x2 + x3/3

so on comparing X coordinates and putting values

1 = 7+2+h/3

3 = 9+h

h = -6

similarly

Y = y1 + y2 +y3/3

putting value and comparing it with y coordinates

5 = -6 + k + 18/3

15 = 12 + K

K = 3

Step-by-step explanation:

Hence,

K = 3

H = -6

Answer 2

actually here you must solve it using the distance formula.the distance between p and (7,-6) and the distance between p and other two points will be equal.thus equate it and u shall get the answer.
