The right answer is C.

Step-by-step explanation:

5x+1+5x+9=180

10x+10=180

-10 -10

10x=170

divide.

x=17

5 (17) +1= 86

5 (17)+9= 94

Answer:

C) 86 degrees, 94 degrees

Step-by-step explanation:

Both of the angles are supplementary, so they add up to 180 degrees.

m<1 + m<2 = 180

(5x+1) + (5x+9) = 180

10x + 10 = 180

10x = 170

x = 17

Now that x has been found, we are able to find the angle measures.

m<1 = 5x + 1

m<1 = 5(17) + 1

m<1 = 85 + 1

m<1 = 86

--------------------

m<2 = 5x+9

m<2 = 5(17) + 9

m<2 = 85 + 9

m<2 = 94
