Answer:
Vz = arccos(0.1673413807) = 80.37º
Step-by-step explanation:
The inverse function of the cosine is the arc cosine.
That means, that if we have that cos a = 1, a is the angle which has cosine equals 1, so a = arccos(1) = 0º.
In this problem, we have that:
cos(Vz) = 0.1673413807
Vz = arccos(0.1673413807) = 80.37º

Answer: C. Ben and Cathy
Step-by-step explanation:
The diagram showing the triangle ABC is shown in the attached photo.
a represents the distance between Ben and Cathy.
b represents the distance between Andy and Cathy
c represents the distance between Andy and Ben,
The unknown angle A is determined by subtracting the sum of angle B and angle C from 180 degrees. This is because the sum of angles in a triangle is 180 degrees.
Angle A = 180 - (55 + 50)
= 180 - 105 = 75 degrees.
75 degrees is the biggest angle and thus, the farthest distance. It corresponds to a, the distance between Ben and Cathy.
