Please help!
victus00 [196]

Answer:

70° is the answer hope it helps

30°+90°+ 3y= 180°

120°+3y= 180°

3y= 180°-120°

y= 60°/3

y= 20°

Now

y°+90°+x°= 180°

20°+90°+x= 180°

x= 180°-110°

x= 70°

nevsk [136]

Answer:

-8° OR 52°

Step-by-step explanation:

Remember 22.

Now, you'll need to take 12 PM and see how many hours it is from 6 AM to 12 PM noon: 6-7, 7-8, 8-9, 9-10, 10-11, 11-12. We have 6 hours from 6 AM to 12 PM.

The problem gives us the average number of degrees it changed: 5. Since it doesn't specify HOW it changed, there are 2 answers.

In order to find the number of degrees it changed, we have to take the hours times the amount given, or in this case, 6 x 5 which equals 30.

Now that we know the fluxation number, we can either add or subtract 30 from the degrees given at noon.

So, 22 - 30 = <em>-8</em> AND 22 + 30 = <em>50</em>.

I hope that helps! :)
