Examine the diagram. Transversal x intersects lines y and z to form 8 angles. The angles formed with line y, clockwise from top left are 1, 5, 6, 2. The angles formed with line z, clockwise from top left are 3, 7, 8, 4. Angle 4 and angle are alternate interior angles.

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.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
