In the trapezoid below, find the values of a and b

a = 139, b = 69

Step-by-step explanation:

Using a property of trapezoids.

Each lower base angle is supplementary to the upper base angle on the same side, hence

a = 180 - 41 = 139

b = 180 - 111 = 69

it would be:

c.parallelogram.

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.
