Brian drew these angles. He uses the equation 180-Y=50. To find the measure of angle Y. What is the measure of angle Y?

130

Step-by-step explanation:

180-130=50  

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.

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values
