Ответ:
The total of interior angles of a polygon is found using the formula 180 x (n-2) where n is the number of sides.
The above figure has 7 sides, so the total of the interior angles is: 180 x (7-2) = 180 x 5 = 900 degrees.
Find X:
Total all angles: 2x+4x+4x+4x+4x+2x+10x = 900
30x = 900
X = 900/30
x = 30
Angle A = 2x = 2*30 = 60 degrees
The answer is A.
Ответ:
See below.
Step-by-step explanation:
A. k = 50 * 3.6 = 180.
B. The equation is y = 180/x.
C. When x = 75, y = 180/75
= 2.4.
D. Checking C: 2.4 = 180/75 = 2.4. Correct
