Find the measure of angle 1.
measure of angle 1 = x
measure of angle 2 = x-6

Angle 1 has degree measurement 48.

Angle 2 has degree measurement 42.

Angle 3 has degree measurement 90 because of the little square there in that spot of angle 3.

Step-by-step explanation:

The measures of angles 1, 2 , and 3 add up to be 180 degrees because they share a common vertex laying on the line given.

Angle 3 has measurement of 90 degrees so this means angle 1 and 2 add up to be 90 degrees.

We are given the measurement of angle 1 and 2:

angle 1+ angle 2= 90

  (x)     +  (x-6)    =  90

  x      +  x-6       =  90

Add like terms:

  2x       -6         =  90

Add 6 on both sides:

 2x                   =    90+6

Simplify right hand side:

 2x                   =    96

Divide both sides by 2:

  x                   =     96/2

Simplify right hand side:

  x                   =      48

x is 48 degrees.

x-6 is 48-6=42 degrees.

Angle 1 has degree measurement 48.

Angle 2 has degree measurement 42.

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!
