Its 5 i did the test and know what the graph looks like :)
Answer:
Step-by-step explanation:
hello :
the ratios 2:1 and 18:9 are equivalent because :
2/1 = (2×9)/(1×9)= 18/9
So
supplementary angles are adding up to 180
lets say they are x and y
x+y=180
x is 59 times y
x=59y
subsitute
59y+y=180
add
60y=180
divide 60
y=3
subsitute
x=59y
x=59(3)
x=177
angles are
3 and 177 degrees
The answer is A. 21.6 just add, 9.2+0.5+6+5.9=21.6
I hope this helps!
I believe the answer is A. 40.
