Two complementary angles must add to 90 degrees, and if you divide 90 into thirds (two parts for the larger angle, one for the smaller), then you get 30 degrees.

If the smaller angle is 30 degrees, then the larger is two times that, which is 60. 60 + 30 = 90, so the larger angle is equal to 60 degrees.

Consider two points in a two dimensional coordinate plane

$(x_{1},y_{1})\text { and } (x_{2},y_{2})$

As you know mid point of a line joining two points is the coordinate of the middle point of only that portion of line joining between two points.

[tex]\text { Mid point of } (x_{1},y_{1})\text { and } (x_{2},y_{2}) =(\frac{x_{1}+x_{2}}{2} ,\frac{y_{1}+y_{2}}{2})[/tex]

As we know distance formula gives the Distance between line joining two points in two dimensional coordinate system.It is always positive.

[tex]\text { Distance formula between two points } (x_{1},y_{1})\text { and } (x_{2},y_{2}) =\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]

Distance formula gives the distance between two points, whereas Mid point formula gives coordinate of the middle point.
