Sam read 20 pages, which is 2/3 of the book. How many pages are there in the book?

30pages

Step-by-step explanation:

20 is 2/3 so 10 is 1/3 so 3/3 is one book

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

283 square feet
