Ok, so 120 pages plus the 60% of the book she has left to read will give the total number of pages.
That means that 120 pages is 40% of the book.
Make a proportion
120/40% = x/60%
72 = .4 x
x = 180 pages
The area is A. 84 square inches
Angles forming linear pair are :
And we know, they are supplymentary
So, the measures of the given angles are :
And
_____________________________
Answer:
5.4
Step-by-step explanation:
Using the pythagorean theorem (a^2 + b^2 = c^2), we can do 2^2 plus 5^2, which is 4 + 25, which simplifies to 29. Now we have 29 = c^2
In order to find c (the hypotenuse), we need to take the square root of both sides to find c. Thus, c = sqrt 29 or 5.385...
Hope this helps!
