4x+60+ x+15=180
5x+75=180
5x=105
x=21
Two linear angles are supplementary thereom
The answer is four
See my handwritten problem worked out in attached pic
71/100 is the lowest the fraction can get
The answer is 32. This is because, first according to The Order of Operations, we do parentheses first (or other grouping symbols). So now the equation looks like this: 8(5 + 11) divided by 4. Next, we add 5 +11, which is 16, so 8(16) = 128, and 128 divided by 4 is 32. I hope this helps! If you need helps on the Order of Operation, please ask! :D
20 degrees if you take a protractor if will come out to the 20
