The midpoint of ab is m (1,3) . if the coordinates of a are (4,1) , what are the coordinates of b

B(-2,5)

Step-by-step explanation:

Let B (x,y)

M = ([Xa+Xb]/2 , [Ya+Yb]/2)

(x+4)/2 = 1

x+4 = 2

x = 2-4

x = -2

(y+1)/2 = 3

y + 1 = 6

y = 6-1

y = 5

B (-2,5)

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

step-by-step explanation:

95.03 is the answer. hope this !
