Answer:
4320 degrees
Step-by-step explanation:
If interior angles are 3960 degrees then there are 24 sides. If polygon is regular, size of each exterior angle is 15 degrees.
A polygon has as many pairs of interior and exterior as number of its sides. Further each pair of exterior and interior add up to
180 degrees.
Sum of all the exterior angles of any polygon is
360 degrees
As sum of all the interior angles of the polygon is
3960 degrees
Sum of all pairs of exterior and interior angles is
3960 degrees + 360degrees = 4320 degrees
The triangle to the top right is missing one angle. We know the sum of all angles in a triangle add up to 180 degrees. We already have 35 + 90 = 125 degrees, so the last angle must be 55 degrees. That angle is verticle to another angle, which you should be able to notice (also 55 degrees because vertical angles are congruent). Now, we have 67 + 55 = 122 degrees in that triangle. It must add up to 180, so the unknown angle is 58 degrees.
Answer:
1x^2+8x
Step-by-step explanation:
Combine like terms
6x^2+(-5x^2)+10x+(-2x)+(-1)+1
1x^2 +8x+0
And there you go
