Question

The midpoint of the coordinates (3,15) and (20, 8) is

A. (23, 23)
B. (11.5, 11.5)
C. (17, 7)
D. none of the above

Answer 1

The question asked to us is about to find the midpoint coordinates of point A(3,15) and B(20,8). To deal with this problem we must know that we have two points through which the line passes.

The standard formula for calculating midpoint is given by,

`:\implies\tt{( (x1 + x2)/(2) ) \: ( (y1 + y2)/(2) )}`

Here we have,

• x1 = 3 and x2 = 20

• y1 = 15 and y2 = 8

Now substituting those values in given formula,

`:\implies\tt{( (3 + 20)/(2) ) \: ( (15 + 8)/(2) )}`

`:\implies\tt{( (23)/(2) ) \: ( (23)/(2) )}`

`:\implies\tt{(11.5) \: (11.5)}`

• The correct ans is (11.5, 11.5) which is option B]

Answer 2

it's B. 11.5,11.5

Explanation:

mid point formulae states that

`(x1 + x2)/(2) , (y1 + y2)/(2)`

`i.e \: (3 + 20)/(2) , (15 + 8)/(2)`

`(23)/(2) , (23)/(2)`

`(11.5,11.5)`
