Step-by-step explanation:
Just plug the equations into desmos the calculator will graph it and show you with colors where the solution is.
Answer:
-0.6
Step-by-step explanation:
-2.1--0.6= 1 1/2
2 negatives make a positive
Answer:
Step-by-step explanation:
<u>Given equation:</u>
<u>Simplify, then solve:</u>
- -11 2/3 * (-4 1/5)
- = -35/3 * (-21/5)
- =
- = 735/15
- = 49.
Your answer is A. 49.
Answer:
A= 41° a=9.84... b=11.32...
Step-by-step explanation:
given B = 49° and C = 90°
and A + B + C = 180
so 49+90+A=180
A= 41°
we also know c (small) is 15 units
and maybe you know this SOH CAH TOA? no, i'm not calling anyone names :P this is just the mnemonic to memorize how sin , cos and tan fit sin(Ф)=Opp/Hyp Cos(Ф)=Adj/Hyp Tan(Ф)=Opp/Adj
Hyp is the hypontenuse of the triangle ( the long side). Opposite (Opp) means the side opposite from what ever angle you are starting at..adjacent (Adj) means what ever angle is next to where you are starting from.
use Cos(49) to find the side a
a is an adjacent side to the 49 angle. We know the Cos and we know the Hyp .. so solve for adj...
Cos(Ф)=Adj/ Hyp
Hyp*Cos(Ф)=Adj
15*Cos(49)= Adj
9.84...=Adj=a
now lets' use sin for the opposite side or b
sin(Ф)=Opp/Hyp
Hyp*Sin(Ф) = Opp
15*sin(49)= Opp
11.32...= Opp =b
Answer:
ithink it should be c
