Can anybody answer this question?
I have difficulty with it.

Alternate Interior Angles are pair of angles on the inner side of each of the parallel lines but on opposite sides of the transversal.

From the above figure the alternate interior angles of the parallel lines pq and rs are:

1) angles a° and c°

2) angles b° and d°

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
