Cot A = 1.96
tan A = 1 / cot A
tan A = 1 / 1.96
tan A = 0.510204082
A = tan^(-1) 0.510204082
A= 27.03086026°
A= 27° 0.03086026°
A= 27° 0.03086026° x (60' / 1°)
A= 27° 1.8516156'
A= 27° 1' 0.8516156'
A= 27° 1' 0.8516156' x (60" / 1')
A= 27° 1' 0.8516156 x 60"
Then the expression for the seconds is 0.8516156 x 60"
In Option A, we have (-0.00120)/(-0.00141) x 60" = 0.851063830 x 60"
In Option B, we have -0.00141/0.00120 x 60" = -1.175 x 60"
In Option C, we have 0.00806/0.01159 x 60" = 0.695427092 x 60"
In Option D, we have (-0.01159)/(-0.00806) x 60" = 1.437965261 x 60"
Answer: Option A: (-0.00120)/(-0.00141) x 60"
46.2
you do 70/100=x/66
then cross multiply so (70•66)=100x
then you get 4620=100x
then you divide both sides by 100 and get x=46.2
7x - 8(-2 + 9) = 112
7x - 8(7) = 112
7x - 56 = 112
7x = 112 + 56
7x = 168
x 168/7
x = 24 <==
Answer:
1080hrs
Step-by-step explanation:

days cancel, redefine week as =5days

weeks cancel redefine 4 weeks = 1 month

months cancel, redefine 9months= 1years

1080hrs per year (if I mathed 120x9 correctly that is, I didn't use a calculator so please double check that 120x9=1080)
Answer: slope(m) for this= 2
m=2
