How to find x in a polygon degrees

Mathematics
1 answer:
snow_lady [41]3 years ago
5 0
To extend that further, if the polygon has x sides, the sum, S, of the degree measures of these x interior sides is given by the formula S = (x - 2)(180). For example, a triangle has 3 angles which add up to 180 degrees. A square has 4 angles which add up to 360 degrees.

Given A(-3, 6) and B(0, 6), what are the coordinates of point P that lies on segment AB, such that AP:PB = 2:1? A: (2, -2) B: (-
DerKrebs [107]

Answer:

(-1 1/2, 6)

Step-by-step explanation:

The mid point between A(-3,6) and B(0,6) represents the coordinates of point P, which is (x,y)

Hence,the coordinates, that is, AP: x = (-3 + 0)/2 = -3/2 = -1 1/2

also, BP: y = (6 + 6)/2 = 6

Therefore, the coordinates of point P = ( -1 1/2, 6)

Find the centre and radius for this circle , x^2+y^2=25
aliya0001 [1]

Answer:

centre = (0, 0 ), radius = 5

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

x² + y² = 25 ← is in this form

with centre = (0, 0 ) and r = \sqrt{25} = 5

A rectangular garden is fenced on all sides with 248 feet of fencing. The garden is 6 feet longer than it is wide. Fine the leng
Shalnov [3]

The total length of the fencing is 248 ft; we call this the "perimeter" of the garden.  Since P = 2W + 2L in general, here:

                       P = 248 ft = 2W + 2(W+6), or   248 ft = 4W + 12.

Subtracting 12 from both sides of this equation:  236 ft = 4W.  Then W = 59 ft, which means that L = 65 ft.
