the sum of the interior angle in a polygon is 40,500° what is the number of sides in the regular polygon
larisa86 [58]

Answer:

227 sides

Step-by-step explanation:

The sum of the interior angles of a convex polygon is S=180(n-2) where n is the number of sides. If S=40500, then we have our equation 40500=180(n-2) and we can solve for n:

40500 = 180(n-2)

225 = n-2

227 = n

Therefore, the number of sides in the regular polygon is 227.

Solve for x in the figure below
Ksju [112]
Since angles A and C are equivalent, then angles B and D must also be equivalent. So if
angle B = angle D then...

7x + 15 = 8x

Now we just solve for x

7x + 15 = 8x
15 = 8x - 7x
15 = x

We Can check to see if it is correct by substituting 15 in for x in the equation..

7x + 15 = 8x
7 (15)+15 = 8 (15)
105 +15 = 120
120 = 120

It checks! angles B and D = 120 degrees
