Answer:
Step-by-step explanation:
54/45 = 1 9/45 = 1 1/5
which is one and one fifth
C.
You take 53.16 and divide by 8.86. Or you can do is add 8.86 over and over until you get 53.16.
The reason is because it takes 8.86 mins to send a report. 6 times 8.86 equals 53.16
Since AED forms a straight line, all involved angles sum to 180°. Therefore AEB + BED = 180. Also, since EC bisects BED, BEC = CED, and BED = 2× CED. Now to substitute the first equation:
AEB + BED = 180
AEB + 2×CED = 180
11x-12 + 2(4x+1) = 180
11x-12+8x+2 = 180
19x-10 = 180
19x-10+10 = 180+10
19x = 190
x = 10
So what is m<AEC?? It is the sum of AEB + BEC, and since BEC = CED we can say that:
AEC = AEB + CED
AEC = 11x-12 + 4x+1 = 15x-11 = 15(10)-11 = 150-11
m<AEC = 139°
