-BARSIC- [3]

Answer:

5.5 Hours

Step-by-step explanation:

Currently, the equation is 60=8.50h+13.25 and h stands for the hours that Sammie worked. So, you need to solve for h by first subtracting 13.25 (his tips) and getting the amount that he received for the hours that he worked.

You should now have 46.75=8.50h

Our final step, is to divide 46.75 by 8.50 to get h by itself and determine the total hours that Sammie worked.

In the end, you should come out with h=5.5, which means that Sammie worked 5.5 hours.

Hello.

The answer is choice A. angle 1 = 118, angle 2 = 118

Explanation:

The four angles above are congruent (meaning the same) to the ones beneath.

Angles 1 and 2 are also congruent, so they will measure the same.

Lets label the angles above A, B, C, D.    B being the known angle, which is 118°. The angles beneath can be labelled E, F, G, H.

∠B ≅ ∠D

∠ABCD ≅ ∠EFGH

∠BD ≅ ∠FH

FH (or 1 and 2) equal 118.
