Step-by-step explanation:
tan(Θ + 30°)
Use angle sum formula:
tan(A + B) = (tan A + tan B) / (1 − tan A tan B)
So we can write this as:
(tan Θ + tan 30°) / (1 − tan Θ tan 30°)
tan 30° = 1/√3, so:
(tan Θ + 1/√3) / (1 − 1/√3 tan Θ)
Multiply top and bottom by √3:
(√3 tan Θ + 1) / (√3 − tan Θ)
PART A
The given vectors are,


The magnitude of the vector

is given by:

This implies that,






PART B
To find the unit vector in the direction of a given vector, we divide by the magnitude of that vector.

Rationalize the denominator.

Also,


PART C
The sketch of the given vectors as well as their unit vectors are shown in the attachment.
