S = (3, 5 )

Step-by-step explanation:

Given the endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ (x₁ + x₂ ), (y₁ + y₂ ) ]

let the coordinates of S be (x, y ), then using the midpoint formula equate the parts to the coordinates of the midpoint M

x = (x + 5) = 4 ( multiply both sides by 2 )

x + 5 = 8 ( subtract 5 from both sides )

x = 3

y = (y + 3) = 4 ( multiply both sides by 2 )

y + 3 = 8 ( subtract 3 from both sides )

y = 5

The coordinates of S = (3, 5 )

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

5x+10 is the correct one

hope this
