Answer:
$1800
Step-by-step explanation:
Total books = 800
Novels Books = 800*2/5 = 320
Nonfiction Books = 800-320= 480
No. of books sold
Novels Books = 320*3/8= 120
Nonfiction Books = 480*2/5 = 192
Total Amount = 120*7 + 192*5
Total Amount = 840 + 960
Total Amount = 1800
Thus total $1800 money the owner of the book shop will make.
Very simple:
As the sides that subtend the angle x are of equal lengths and are joined to form a triangle, we know the only other angle (the blank one) is going to also be 56° and since angles in a triangle always add up to 180°, we just have to do:
180 - (2 × 56) = 68°
Combine like terms to solve the equation
The 3 angles of a triangle, when added, = 180 degrees
so if 2 of them are 70.....70 + 70 = 140
then the 3rd will be 180 - 140 = 40 degrees <==
