Find cos(theta) if theta is in the first quadrant and tan(theta) = 40/9

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.

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
