Answer:

The triangle angle rule says that all of the angles in a triangle will add up to equal 180. So to find x we subtract the given angles ( 45 and 60 in this case) from 180.

x = 180-60-45

180-60-45=75

so x = 75

To find y we know that angle x and and y are angles formed on a straight line that are split up by a triangle segment. These angles are called supplementary angles which add up to equal 180.

So knowing that angle x = 75 we can find angle y by subtracting 75 from 180

180-75=105 so y = 105

Another way we could solve for y is the exterior triangle rule

This rule states that an exterior angle of a triangle is equal to the two opposite interior angles

so y = 45 + 65

45 + 65=105

so y = 105

There are 4,000 books in the town's library. Of these 2,600 are fiction. Write a percent equation that you can use to find the p
defon

Answer:

x = (2600/4000) × 100%

x = 0.65 × 100%

x = 65%

Step-by-step explanation:

The percentage equation that can be used to find the percent of books that are fiction can only be found where the number of fiction books is known and the total number of books available is known as well.

Given;

Number of fiction books = 2,600

Number of books = 4,000

let the percent of books that are fiction be x

x = (2600/4000) × 100%

x = 0.65 × 100%

x = 65%
