Answer:
55
Step-by-step explanation:
Because of the parallel lines (marked by those arrows) we know that the corner angles are the same:
110 - x = x so
110 = 2x
55 = x
2.8 or if rounded to the nearest tenth so 2.8√8
Answer:
21
Step-by-step explanation:
Similar triangles. MNL is just ABC but 3/4 the size.
x = 8*3/4 = 6
perimeter woudl be 6+6+9 = 21
Solution :
The data is normally distributed.
The standard deviation is 18 days
Here the data is normally distributed and 54 days is 3 days of standard deviation.
Therefore, the percentage of the births that would be 
within the 54 days of the mean 
length is given by :
= P( -3 < Z < 3)
= 0.9544
= 95 %
Therefore, about 95% of the births would be within 54 days of the men length.
