30, multiply 4 by 2.5 to get 10, then multiply 12 by 2.5 to get 30 (or x).

Hi Brainiac 4/12 = 10/x Use cross multiply 4x = 120 Divide both sides by 4 4x/4 = 120/4 X = 30 The answer is A I hope that's help :)

Can someone give me some tips of how to study. I have already tried writing everything in my lesson but it doesn't seem to work

Study all notes, reread the chapters again. Have someone ask questions on the chapters page by page. This always has worked for me. Plus try to do this again the night before the test. You will be surprised how much you can remember by doing it again the night before the test. Hope this helps.

Find the measure of the exterior Angle1 (I’m a bit confused on how exterior angles work)

Answer:

Step-by-step explanation:

I would do 40 + 30 = 70

180-70 = 110

110 is the last angle bc all angles add to 180 in a triangle

Then 180 - 110 = 70 for angle 1 because their supplementary

I don't know if you could just add the 2 inside angles but I would do it this way to be safe until I know for sure.
