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? a. 82.21° b. 84.46° c. 85.11° d. 86.13°

450 is the final answer! : )

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
