You got this or do I?

silvernight269:

i got this but if you want you can do this one

silvernight269:

So basically AC is the diameter. Meaning its half the circle. What degree is half a circle?

Nicole:

180

darkknight:

Well we know that a circle is 360 degrees all around. Which means that it is 180 degrees in a straight line. You want to solve for x. You can do so by doing 6x+5x+8x=180 , combine like terms, solve for x. Then plug that value that you got for angle EQD

silvernight269:

Exactly.

darkknight:

Tell me if you are lost anywhere

Nicole:

So 6x+5x+8x=180. x=9.47

Nicole:

Now im lost lol

silvernight269:

So basically how Darkknight said, the 3 angle make up 180. so you add them and make it equal to 180.

darkknight:

^, so we know x is 180/19. Plug that in for x in the angle EQD. Then you will get the angle you need to find

darkknight:

So you know that the angle is 5x right? So plug in your value of x into there and then solve for the angle

silvernight269:

You technically got it right. Plug in the value of x into the angle equation and you have your angle degree

Nicole:

Okay so when you say "plug in the value of x into the angle equation" what angle equation.

silvernight269:

the angle that they wish for you to find

darkknight:

So you want to find the angle for EQD. That is 5x if you see the image. YOu want to plug into that

darkknight:

You know x, now you want to find angle EQD. So put plug value of x into the angle EQD eqn, which is 5x. Making your answer 5(9.47)

Nicole:

Ohh okay that makes sense since EQD is 5x we plug in x obviously which would be 5(9.47 which would be 47.35

darkknight:

exactly!

Nicole:

Idk who to give the best response thingy to because both of you were helpful

silvernight269:

its fine lol.

darkknight:

Its fine. Give it to silver because s/he is a goat

Nicole:

I mean I got other questions so its fine yes

Nicole:

I mean I got other questions so its fine yes

silvernight269:

wut u mean im a goat lmao
