Answer:
C) 65 degrees
Step-by-step explanation:
Both of the angles given are supplementary angles meaning the equal 180 degrees. So you format it as (28x + 3) + (17x - 3) = 180. Simplify the equation to get 45x = 180. Divide 180 by 45 to recieve 4. We now know x is equal to 4. Plug 4 into x for 17x - 3 to get 17(4) - 3. Which equals 65.
