I really need help with this one, I've been asking the same question like three or four different kinds. Can someone please help me I can't figure it out​

140

Step-by-step explanation:

The sum of one interior angle and one exterior angle is 180

180-40=140 so an interior angle of the regular polygon would be equal to 140

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.
