Answer:
37.7
Step-by-step explanation:
EF and ED define the Tangent of D
Tan(37) = side opposite D / side adjacent to D
Opposite means a line (FE) that is not connected to the angle. It is never the longest line (hypotenuse) in a Right Triangle
Adjacent means the leg that is connected to the angle, but is not the hypotenuse.
Tan(D) = opposite over adjacent
Opposite = x
Adjacent = 50
Tan(37) = 0.7536 rounded to 4 places, but I've kept the exact value in my calculator.
0.7536 = x / 50 Multiply both sides by 50
0.7536*50 = x
x = 37.6777
The nearest 1/10 is 37.7

<u>Step-by-step explanation:</u>
a) x ≤ 0 so, f(-5) = | -5 | = 5
x ≤ 0 so, f(-3) = | -3 | = 3
x > 0 so, f(5) =

Answer:
x= first number y= second
x=2y+9 and x+y=129, these are the equations...solving gives x=89,y=40

Answer:
La cantidad de dinero
Celia tiene = x = 9.33 €
Quique tiene = y = 4.67 €
Step-by-step explanation:
Representemos la cantidad de dinero
Celia tiene = x
Quique tiene = y
Entre Celia y Quique suman 14 €.
x + y = 14
x = 14 - y
Si Celia tuviera 1 euro, tendría el doble de dinero que Quique.
Por lo tanto,
x = 2 años
Nosotros sustituimos
2y + y = 14
3 años = 14
y = 14/3
y = 4.67 €
x = 14 € - y
x = 14 € - 4.67 €
x = 9.33 €
Por lo tanto,
La cantidad de dinero
Celia tiene = x = 9.33 €
Quique tiene = y = 4.67 €
