Answer:
Sin(F) = 12/13
Cos(F) = 5/13
Tan(F) = 12/5
Step-by-step explanation:
Sin = Opp./Hypo, Cos = Adj./Hypo. and Tan = Opp./Adj.
So
Sin(F) = Opp./Hypo = 12/13
Cos(F) = Adj./Hypo = 5/13
Tan(F) = Opp./Adj. = 12/5
N - 18 = -6
n - 8 = -6
+ 18 + 18
n = 12
E = 7
F = 8
G = 1
First find a number that multiplies by 4 to make a number ending in 2. The options are either 3 or 8.
Try the full multiplication with both 3 and 8 and see which one works.
Using 3 works up until you try and work out E as E would have to be a two digit number for it to work so therefore the answer to F must be 8.
Hope this helped.
