If cosVz=0.1673413807, find Vz.<br> Thanks- thold you it was easy.
12345 [234]

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

Olegator [25]

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.
