Answer:
49 degrees
Step-by-step explanation:
m < D = 90 - m < O (right triangle rule)
m < D = 90 - 41
m < D = 49

SLOPE OF THE LINE:- (y2-y1)/(x2-x1)
here x1= 0 , y1 = 3 , x2 = -1 , y2= 4
Now Slope :- (4-3)/(-1-0)
Slope :- -1

The equation for the sum of interior angles is :
Sum = (n-2) x 180, where n is the number of sides.
Replace sum with the given sum:
3960 = (n-2) x 180
Divide both sides by 180:
22 = n-2
Add 2 to each side:
24 = n
It has 24 sides.
For Each interior angle, divide the total sum by the number of sides:
3960 / 24 = 165 degrees
The interior and exterior angle needs to equal 180 degrees. To find the exterior angle, subtract the interior angle from 180:
180 - 165 = 15 degrees.
