x=m(y-k)^2+h\\\\(h,\ k)-the\ vertex

We have the vertex (-4, -1), therefore we have:

x=(y-(-1))^2-4\ \ \ |+4\\\\(x+4)=(y+1)^2

Angle 1 and 2 are supplementary. Angle 1=3x° angle 2=(2x. -25)° select from the drop down menu
goldfiish [28.3K]

Answer:

x = 41°

∠1 = 123°

∠2 = 57°

Step-by-step explanation:

If angles 1 & 2 are supplementary, that means...

\angle1 +\angle2=180\textdegree

To find the value of each angle, you first must find the value of x by plugging in the values of both angles...

\angle1 +\angle2=180\textdegree\Longrightarrow3x+(2x - 25) = 180\textdegree

First, combine like values, then subtract add 25 to both sides.

3x + 2x = 5x\Longrightarrow 5x - 25+ (25) = 180 + (25)\\\\5x=205

Then, divide both sides by 5, and plug the value of x into the original equations for angles 1 & 2.

\frac{5x = 205}{5}\\\\x = 41\textdegree\\\\\angle1= 3x = 3(41) = 123\textdegree\\\\\angle2=2x-25=2(41)-25=82-25=57\textdegree

Can someone plz help me I’m tryna go to sleep .
schepotkina [342]

Take a warm shower, however you want, dont eat too much before hand, relax your face and don’t think too much about it, dont think much just think “im sleepy im going to sleep”
Incase you don’t want to read all of this


It seems like you’re stressed especially since you’re thinking about it too much to the point you have to use brainly. You’re stressed and need to relax and not think too much, you might be having too much things going around you and or many possibilities. For me I just take a warm shower and just stay and think, probably cry if i have to, without sleep or little you’re going to be anxious and things bother you more and makes sleeping even more harder on top of that
