-4
8/2 = 4
A negative times a positive is negative so it’s
-4
So so the sides are x, x√3, 2x
here is an attachemtnt don't mind the one on the left
Answer:
The proportion of memory sticks that will be scrapped is 0.3 = 30%.
Step-by-step explanation:
Uniform probability distribution:
An uniform distribution has two bounds, a and b.
The probability of finding a value of at lower than x is:
The probability of finding a value between c and d is:
The probability of finding a value above x is:
Distributed uniformly between 3mm and 13 mm.
This means that 
Calculate the proportion of memory sticks that will be scrapped:

The proportion of memory sticks that will be scrapped is 0.3 = 30%.
Tanα=y/x
α=arctan(y/x), we are given the point (3.2, 6.2) so:
α=arctan(6.2/3.2)°
α=arctan(1.9375)°
α≈62.7° (to nearest tenth of a degree)
180 is the least common multiple.
