If you have a slope of -4 then it would be -4/1 because rise/run. If it were -4/-1 then the slope would be 4.
Answer:
x ≥83%
Step-by-step explanation:
77%+x/2=80% (×b.s by 2)

x=160%-77%
x=83%
Answer:

Answer:
48/73
Step-by-step explanation:
cos S in ratio = ?
cos S = Adjacent/hypothenus
adjacent is the dimension of line aside the opposite (the line facing angle S, the hypotenus(longest line)
adjacent = 48
hypothenus = 73
cos S= 48/73
