Plsss help me on this (:

x = 39 degrees

Step-by-step explanation:

Both of the angles are vertical angles. Therefore, they are the same magnitude.

2x+1 = 79

2x = 78

x = 39

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.
