Question

Answer for a lot of points lololol

Answer 1

3(13) + 7 = 46

9(13) + 17 = 134

Which concludes that your answer is A!

Answer 2

If the two angles are a linear pair, this means that they are supplementary and both add up to 180 degrees. So set up the equation:

3x + 7 + 9x + 17 = 180

--> 3x + 9x + 17 + 7 = 180

--> 12x + 24 = 180

-->12x = 180 - 24 = 156

-->156/12 = 13, so x = 13

Plug in the x value:

3(13) + 7 = 46 degrees

9(13) + 17 = 134 degrees

To check your work, 134 + 46 = 180.

Your answer is A.
