Answer:
He bought 17 books.
Step-by-step explanation:
Given that:
Total money spent = $89
Cost of each book = $5
Shipping price = $4
We have to find, Total number of books
So if the number of books be represented by b, the equation will become:
Cost of one book * total number of books + shipping price = total money
Putting values we get:
5*b + 4 = $89
By simplifying:
5*b = 89 - 4
5*b = 85
Dividing both sides by 5 we get:
b = 17
So the total number of books bought is 17.
i hope it will help you!

x=9y=45°
Step-by-step explanation:
x=9y (being the base angle of triangle)
or, x+90+9y=180 (sum of angles of triangle)

or, 2x=180-90
or, x=90/2
x=45°
so, x=9y=45°
