The angles shown below are supplementary: a pair of supplementary angles is shown. one angle measures 10x and the other angle measures 60 degrees. what is the value of x? 6° 9° 12° 18°

Option C, 12°

Step-by-step explanation:

When a pair of angles are supplementary that means their sum will be equal to 180°.

By this definition 10x + 60° = 180°

                            10x = 180 - 60

                            10x = 120°

                                x = 12°

Option C, 12° is the answer.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48
