Answer:
-2.44
Step-by-step explanation:
Is a right angle triangle
We apply SOHCAHTOA
SOH is sin=Opposite divided by Hypotenuse
CAH is cos=Adjacent divided by Hypotenuse
TOA is tan=Opposite divided by Adjacent
so in this case,cos is the right thing to use
Therefore,x=adjacent
15=Hypotenuse
angle=52°
Cos(52)=x÷15
making x the subject,
x=15cos(52)
x= -2.44
Answer:
2080
Step-by-step explanation:
The solution to these equations might best be found using Cramer's Rule. It tells you ...
x = (56939×3 -41655×2)/(-236×3 +838×2) = 87507/968 ≈ 90.400
This is years after 1990, so the year the incomes become the same is predicted to be ...
1990 +90.4 = 2080.4
The median incomes will be the same in the year 2080.
Answer:
x = C+d-r
Step-by-step explanation:
C - x = r - d
-x = r - d - C
x = -(r - d - C)
x = -r+d+C
x = C+d-r
The side length of the square is also 1.
