Answer:  The required co-ordinates of the midpoint S are (-1.5, 2).  

Step-by-step explanation:  Given that S is the midpoint of a line segment QR, where the co-ordinates of he endpoints are Q(-5, 5) and R(2, -1).

We are to find the co-ordinates of the midpoint S.

We know that

the co-ordinates of the midpoint of a line segment with endpoints (a, b) and (c, d) are

\left(\dfrac{a+c}{2},\dfrac{b+d}{2}\right).

Therefore, the co-ordinates of the point S are

\left(\dfrac{-5+2}{2},\dfrac{5+(-1)}{2}\right)\\\\\\=\left(\dfrac{-3}{2},\dfrac{4}{2}\right)\\\\=(-1.5,2).

Thus, the required co-ordinates of the midpoint S are (-1.5, 2).

Answer:

(-1.5, 2)

Step-by-step explanation:

Add both x coordinates, divide by 2.

(-5) + 2 = -3

-3/2 = -1.5

Add both y coordinates, divide by 2.

5 + (-1) = 4

4/2 = 2

Each exterior angle of a regular polygon is 10°. How many sides does it have?
jeka94

Answer:

if exterior angle is 10 degrees, then interior angle is 180 -10 = 170 deg.

Each trinaglke inside the polygon will be isosceles with two angles of 170/2 - 85 degrees each.

So, angle at centre = 180 -170 = 10 deg.

Ttal angle at centre = 360 deg.

No of sides = 360 /10 = 36 sided polygon.

b) Sum of interior angles is given by (2N-4) Right angles

So: 9900 = (2N-4)x90 = 180N - 360

180N = 9900 +360 = 10260

N = number of sides = 10260 / 180 = 57 sides
