Vector u has a magnitude of 5 units and a direction angle of 30°. vector v has a magnitude of 7 units and a direction angle of 120°. what is the direction angle of their vector sum?

Nearly 84°

Step-by-step explanation:

In the attached diagram

So, angle BAC = 120° - 30° = 90°

A parallelogram ABCD is a rectangle, its diagonal vector AD is the sum of vectors AB and AC.

Consider right triangle ABD. In this triangle

So, the sum vector AD has direction 30° + 54° = 84°

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
