-3x+7

Step-by-step explanation:

The entire function f is being multiplied by -1, -1 isn't being plugged in for x in this case.

f -1(x)= -1(3x-7)

f -1(x)= -3x+7

I'm going to take a guess and say 60, and the reason I say 60 is because I just thought 180 / 60 LOL

Answer:

x=20 degrees

Step-by-step explanation:

So, lets recall some things.

First off, opposite angles are the same.

So this would make x equal 20.

But lets test this.

When you look at a X, or any other sort of two lines that cross each other, can you ever think of a time when one side is not the same as the other? No.

This is because when you change one angle, since the lines are crossed together, it will change the opposite angle. This change will always be constant as long as the two lines connect at the same point

So if you changed a 10 degree angle of two lines, so that it was 30, this would change for the other line.

I attached a image below.

I hope this explains this to you and helps! :D

==================================================================

Respuesta:

x = 20 grados

Explicación paso a paso:

Entonces, recordemos algunas cosas.

En primer lugar, los ángulos opuestos son iguales.

Entonces esto haría que x sea igual a 20.

Pero probemos esto.

Cuando miras una X, o cualquier otro tipo de dos líneas que se cruzan, ¿puedes pensar alguna vez en un momento en el que un lado no sea igual que el otro? No.

Esto se debe a que cuando cambia un ángulo, dado que las líneas se cruzan, cambiará el ángulo opuesto. Este cambio siempre será constante siempre que las dos líneas se conecten en el mismo punto

Entonces, si cambia un ángulo de 10 grados de dos líneas, de modo que sea 30, esto cambiaría para la otra línea.

Adjunto una imagen a continuación.

¡Espero que esto te explique esto y te ayude! :D

Find the missing SIDE "X".
Marysya12 [62]
Ughh trig
I think what you gotta do here is use tangent because you are dealing with opposite and adjacent. Doing tan(41) will give you x/10. tan(41) is 0.8692... and you can just multiply that by 10 because x is being divided by 10, so x is around 8.69.
Now, with the two legs, you can use Pythagorean theorem to find the hypotenuse.
You already have 2 angles (right angle and the angle we just used to find x) so we can use the fact that all triangle angles add up to 180 to do 180-90-41.

In the end, x ends up being around 8.7, the hypotenuse around 13.3 and the last angle 49 degrees.
