31=2y-5
Add 5 on both -5+5 which cancels out and 31+5 which is 36 and then divide 36 by 2 which equals to 18.
So y=18 hope this helped (':
Answer:
are you doing mathematical models a too?
Step-by-step explanation:
Answer:
Sin(R) = 15/17
Cos(R) = 8/17
Tan(R) = 15/8
Step-by-step explanation:
Sin = Opp./Hypo, Cos = Adj./Hypo. and Tan = Opp./Adj.
So
Sin(R) = Opp./Hypo = 60/68 = 15/17
Cos(R) = Adj./Hypo =32/68 = 8/17
Tan(R) = Opp./Adj. = 60/32 = 15/8
Mapping A would be the one
