Complementary angles = 90
x+y =90
y=x+24
substitute this in to the equation
x+x+24=90
2x+24=90
subtract 24 from each side
2x = 66
divide by 2
x=33
y = 33+24
y=57
Answer: 33, 57

Answer:
a is equal to 3 ...................
There are 20 books in each box.
If each box has 20 books, then the number of books is 20 times the number of boxes. (20 books: 1 box, 40 books: 2 boxes...)
So, using mathematical terms, the number of books is equal to the number of boxes x 20.
Here, it says James packs x boxes of books. This means that we call the number of boxes, x. X could be 1,2,3, or any other number.
So, since there are 20 times as many books as boxes, the number of books is 20 times x.
In math terms, this is written like 20x.
So the answer is 20x.
A number rounded to the nearest 10000, means that the last four digits of that number (on the left of the decimal point) are 0.
<span>However, if the fourth-last digit to the left of the decimal point is 5 or greater, the number to the left of that is rounded to 1 number higher. For example, if you were rounding 145293 to the nearest 10000, it would be 150000.
However, the </span>fourth-last digit to the left of the decimal point in this case is 1.
Therefore, <span> 21000 rounded to the nearest 10000 is 20000.
