Firstly, a straight line = 180 degrees.
Based on the statement above, we can create an equation of 180-95 = x
(Which is 85)
Now, we also know that all of the angles in a triangle add up to 180 degrees, so we can create this equation of 180- (85 + 50) = y
(Which is 45)
Answer:
0.83

Elementary nostoligia :)
The measure of any interior angle of a convex regular n-gon is :
180 º - ( 360 º / n )
For a 30-sided polygon,
interior angle = 180 º - ( 360 º / 30 )
..................... = 180 º - 12 º
..................... = 168 º
The fence must have two sides of length 45.45 ft and two sides of length 14.63
To cover each of 45.45 ft long side, he will need 45.45 / 2 = 22.7 slats which approximates to 23. So, they are 2 * 23 = 46 slats.
To cover each of 14.63 ft sides, he will need 14.63 / 2 = 7.3 which approximates to 8 (to not leave any spaces between each slat). So, they are 2 * 8 = 16 slats.
That makes 46 + 16 = 62 slats.
Answer: around 62 slats.
