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>
Answer:
x is 90 z is 60 and y is 30

Answer:
8 rides
Step-by-step explanation:
20 + .50x = 24
-20 -20
.50x = 4
/.50 /.50
x = 8
