Answer:
Sum of 2 3/8 + 5 1/4 = 7 5/8
-4x - 2.4
explanation: 1.3 - 3.7 = -2.4
then you leave the -4x by itself since it’s the only variable
In this problem you use cosine because you know the hypotenuse and you want to know the adjacent side of the triangle. So in your calculator you would input cos(52). Then you would multiply that answer with the hypotenuse side. So your equation would be this: cos(52) x 13
First, 10 1/2 is the same as 21/2
If there are 12 inches in a foot then
21/2*12=126 inches
