La distancia de la casa de Juan a la tienda es de 25 metros, ¿cuántos decámetros hay?.La distancia de la casa de Juan a la tiend
scZoUnD [109]

Answer:

<u>Hay 2.5 decámetros en 25 metros.</u>

Step-by-step explanation:

Aqui solo debemos recordar la relacion de metros a decámetros.

1 decámetro = 10 m

Entonces 25 metros seran:

\frac{1\: decametro}{10\: m}=\frac{x\: decametro}{25\: m}

x=\frac{25\: m*1\: decametro}{10\: m}

x=\frac{25*1}{10}=2.5\: decametros

<u>Por lo tanto, hay 2.5 decámetros en 25 metros.</u>

Espero te haya sido de ayuda!

If sin x = 12÷13 where 0° &lt;x&lt;90°<br>find the value of 1-cos ×cos( x)​
s2008m [1.1K]

Answer:

This is how tackle this type of problem:

Draw a right triangle with the indicated sides: side opposite the angle = 12 and hypotenuse = 13

Then, calculate the 3rd side by Pythagoras: x2 + 122 = 132

x2 = 169 - 144

x2 = 25

x = 5

Now, we have all 3 sides of our diagram triangle, so we can find all the trig ratios for the angle.

Next, we use the double angle formula to simplify cos(x + 30) = cos x cos 30 - sin x sin 30

= 5/13 . √3/2 - 12/13 . 1/2

= 5√3 /26 - 6/13

= (5√3 - 12) / 26

Step-by-step explanation:
