Answer:
cos(2sin−1x)=1−2x2
Step-by-step explanation:
et sin−1x=θ , so that, x=sinθ,|x|≤1,θ∈[−π2,π2].
Answer:
she uses 72 gallons
Step-by-step explanation:

Answer:
Step-by-step explanation:
x+118 degrees =180 degrees
x +118 degrees-118degrees =180 degrees - 118 degrees
x =62 degrees
The meaning of the question is
Let the unknown number be x
Therefore x+7=16-2x
Now 2x+x=16-7
3x=9
X=9/3
x=3
