Step-by-step explanation:

Angles 3 and 5 are on the same side of the transversal, between the parallel lines, so can be called "same-side interior angles". These are also called "consecutive interior angles". As such, they have a sum of 180°, so are also "supplementary angles." We don't know what your pull-down menu options are, but perhaps one of these descriptions is on there.

Because the angles are supplementary, their sum is 180°. So, the equation ...

  (3x +4)° +(2x +11)° = 180°

can be used to solve for x. Likewise, any of the possible simplifications of this can be use:

  (3x +4) +(2x +11) = 180 . . . . . divide by degrees

  5x +15 = 180 . . . . . . . . . . . collect terms

  5x = 165 . . . . . . . . . . . . . subtract 15

  x = 33 . . . . . . . . . . . . . . divide by 5

Once we know that x=33, then the measure of angle 5 is found from its expression:

  m∠5 = (2x +11)° = (2·33 +11)°

  m∠5 = 77°

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
