To get the number of standard deviation that 77 is from the mean, we get the z-score:
z-score is given by
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
thus the value of z from the information above is:
x=77
μ=58
σ=7
z=(77-58)/7=2.7143
41 because if you separate the parts the square and the triangle then you would have a square that is 16 sq in diameter and a triangle that is 25sq in diameter

ANSWER
Option D is correct
EXPLANATION
We resolve the forces into component forms.


Also the second is resolved to obtain,


To find the resultant vector, V, We add the corresponding components of the two forces to get:


The correct answer is D.
No.
4 meters is 400 centimeters, so is smaller than 450 centimeters.
