Answer:
x=46
Step-by-step explanation:
subtract 13 from both sides
x=59-13=46
Triangles add up to 180. So add up the two angles given, and subtract that from 180. That will be x!
Answer: 122?
Step-by-step explanation: i used a protractor (im not the best at that though but im 89% sure i'll be honest
Lets set up the relationship of the length to width:
l = 3w
Using this, we can make all the variables the same by substitution:
2l + 2w = perimeter
2l + 2w = 72
2(3w) + 2w = 72
6w + 2w = 72
8w = 72
w = 9
The width is 9, to the length must be 9*3, or 27.
Hope this helped!
68-11=57 (Yesterday's temperature)
That's the expression. ^^ And yesterday's temperature is 57 because, 68 degrees (Today's temperature) minus 11 degrees (how many degrees colder it was yesterday) is equal to 57 degrees (Yesterday's Temperature).
