To solve your question, you add all of the measurements together, set them equal to 180, solve for x, and plug x back in for whichever angle they are asking for; in this case, they want angle R
7x + 12x + 20 + 20x - 35 = 180
39x - 15 = 180
39x = 180 + 15
39x = 195
x = 5
Angle R = 12x + 20
12(5) + 20
60 + 20
80
Option C is your answer.
Well lets remember that a square has four sides that are all equal.
So if we know one side, we know them all!
And perimeter is all of the sides added up.
Well.. 4 sides that are all 9 meters long? here's the math!
9 + 9 + 9 + 9 = 36
Your coffee shop is 36 meters long
Good Luck! :)
I think you forgot to put the image in the question
You could move the decimal to the right 6 times
0.2 x 10^6
0200000 or 200,000(remember that if there's only two digits there will be one less zero than the exponent)
29/5 is 5.8 5.8 dividen by 9 1/2 is 0.61052631578
Hope this helps! Have a great day!!!
