If one of the exterior angles is 40, you can find its adjacent interior angle by subtracting 40 from 180. This is 40, so the triangle has 2 interior angles that are equal to 40. Now we have 2 of 3 interior angles. The sum of the measures of the interior angles of a triangle is 180, so we can set this equation up:
x + 40 + 40 = 180
x + 80 = 180
x = 100
So the triangle's angles have measures of 40,40 and 100 degrees.
The answer to this problem would be 2.5.
F= kx
so to get k divide both sides by x
so k = F/x
To find the rate you need to divide 15 by 1/8 and you get 120 pages per hour as your answer
