Answer:
14
Step-by-step explanation:
(11/3)/(1/4)=14 2/3 which means you can make 14 complete bows
Fine but I ain't showing my work completely.
The sum of all ext. angles of a polygon = 360.
So, you make this formula and solve for x.
360 = 49 + (3x+30) + (14x+6) + (6x-3) + (4x+8)
360 = 49 + 27x + 30 + 6 -3 + 8
360 = 90 + 27x
270 = 27x
/27 /27
10 = x
Now substitute for angle A, which is (6x-3)
6x-3
6(10)-3
60-3
57
Therefore, angle A is 57 degrees.
Answer: y > 4.5 or y < -4.5
You use the rule
if |y| > k, then y > k or y < -k
where k is some positive number. In this case, k = 4.5
