Answer!! Whoever has the best answer I'll give brainliest!!

RoseWind [281]

There are 2 ways to do this. I'm going to do it the way that I think is most simple.

You have to find their LCM which is 40. Now times 40 to 1/4 v and 7/10

The equation then becomes 10+40v=28

You simplify it: 40v=18

v= 9/20

Una antena de televisión será sujeta con un cable de 6 m de longitud de la parte superior de la misma, a una argolla que se encu

mylen [45]

Answer:

5.196 m

Step-by-step explanation:

p = La perpendicular del triángulo es la longitud de la antena.

h = La hipotenusa del triángulo es la longitud del cable conectado a la parte superior del poste = 6 m

$\theta$ = Incline el cable con el suelo = $60^{\circ}$

De las funciones trigonométricas sabemos que

$\sin\theta=\dfrac{p}{h}\\\Rightarrow p=h\sin\theta\\\Rightarrow p=6\times \sin60^{\circ}\\\Rightarrow p=6\times\dfrac{\sqrt{3}}{2}\\\Rightarrow p=3\sqrt{3}\\\Rightarrow p=3\times 1.732=5.196\ \text{m}$

La longitud de la antena es 5.196 m.
