Answer:
1877 computer users
Step-by-step explanation:
We have that for 95% of confident, the value of z has a value of 1.96 (attached table about it), they also mention the margin of error (E) that is 10 and finally the standard deviation (sd) that has a value of 221.
We apply the following formula:
n = [z * sd / E] ^ 2
replacing:
n = [1.96 * 221/10] ^ 2
n = 1876.27
that is, the minimum sample size is 1877

The measure of all the three angles is given below.
What is an angle?
An angle is a figure in Euclidean geometry created by two rays, called the sides of the angle, that share a common termination, called the vertex of the angle. Angles created by two rays are located in the plane containing the rays. Angles are also generated when two planes intersect. These are known as dihedral angles. An angle defined by two intersecting curves is the angle of the rays lying tangent to the respective curves at their point of junction.
Measure of Angle 1 = 143°
Measure of Angle 2 = (180-143)° = 37° (Linear Pair)
Measure of Angle 3 = Measure of Angle 1 = 143° (Vertically opposite angle)
Measure of Angle 4 = Measure of Angle 2 = 37° (Vertically opposite angle)
