Supplementary angles are angles that are adjacent to each other and when summed to get a total of 180 degrees. In this case, DEF and FEG are supplementary. Thus the equation is <span>9x +1 + 8x + 9 = 180 = 17 x + 10; x then is equal to 10 so
<</span>DEF = <span>9*10 +1 =91 degrees
</span><FEG = <span>8*10 + 9 = 89 degrees</span>
You would need 24 machines
Because 1 machine makes 5 envelopes per minute so simultaneously 24 machines can make 120 envelopes per minute.

Answer: hi
Step-by-step explanation:
The GCF of both numbers is 9. So 9 goes outside the parentheses. The numbers multiplied by the GCF to get 36 and 45 are 3 and 5. The answer is 9 ( 3 + 5 )
