Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
so Sin(x) = d/f
Cos(x) = e/f
Tan(x) = d/e
got it? :)
If itt says 4×3+6 it is 18 and it means you can either multiply first
Answer:
X^2+6X-7=0
Step-by-step explanation:
To identify the quadratic equation use the following method
(X-a)(X-b)=0
Where
a=-7
b=1
(X+7)(X-1)=0
X^2+7X-X-7=0
X^2+6X-7=0
