THe first thing we need to do is find the hypotenuse. From the tangent we know that the legs of the right triangle are 3 and 4. So this 2/3 of a special right triangle (3-4-5). Thus the hypotenuse is 5. The sin is defined as

. We know the opposite is 4 and hypotenuse is 5. Thus the sin is
Answer:
Tienes 3 números, "x", "y", "z"
=> El primero es 20 unidades menor que el segundo:
El primero es "x", y el segundo es "y", entonces:
x = y - 20
=> El tercero es igual a la suma de los dos primeros:
El tercero es "z", entonces:
z = x + y
z = (y - 20) + y
z = 2y - 20
=> Entre los tres suman 120
x + y + z = 120
y - 20 + y + 2y - 20 = 120
4y - 40 = 120
4y = 160
y = 40
Si y = 40, entonces:
x = y - 20
x = 20
Además, z = 2y - 20
z= 60
RPTA:
x=20
y=40
z=60

Answer:
multiplication
Step-by-step explanation:
The evaluation of ...
13 -2·3 +4/4 +4
starts with the multiplication, because there are no exponents or parentheses.
13 -6 +4/4 +4
Next is the division:
13 -6 +1 +4
Finally, the addition and subtraction:
7 +1 +4
8 +4
12

We have assumed your x is not a variable, but is intended to indicate multiplication. We have also assumed that your "divided by" implies no particular grouping, so that the numerator is the first preceding number and only the first following number is in the denominator.
Move over 2 decimal places
This would be 38.4%
