Answer:
The correct answer is - option b. 90.6
Explanation:
The scalar x-component of a vector can be expressed as the product of its magnitude with the cosine of its direction angle
If you shine a light straight down onto that vector, then the length of its shadow on the x-axis is -
x-component = 112· cosine(36°)
x-component = 112 · (0.8090)
x-component = 90.60
Thus, The correct answer is - option b. 90.6
