Question

What is the length of the x-component of the vector shown below?

A. 72.5
B. 8.1
C. 23.6
D. 34.1

Answer 1

Option B. 8.1

Step-by-step explanation:

From the question given above, the following data were obtained:

Angle θ = 71°

Hypothenus = 25

Adjacent = x

Thus, we can obtain the x component of the vector by using the cosine ratio as illustrated below:

Cos θ = Adjacent /Hypothenus

Cos 71 = x/25

Cross multiply

x = 25 × Cos 71

x = 25 × 0.3256

x = 8.1

Therefore, the x component of the vector is 8.1
