Match each θ with its corresponding quadrant location 1. cos θ= -15/13, tan θ is negative

2. tan θ= 3/4, sec θ is negative

3. cot θ= -3π/2 ≤ 0

4. csc θ= -2, cot=-√3

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
