Sin < O = 10/15 = 2/3
so m < O = 41.8 degrees
m < Y = 90 - 41.8 = 48.2 degrees
-2 then -1 then 0 1 2 so it is 2
Answer:

Step-by-step explanation:
It can be found by integral.
First let's find the intersection points.

Only intersection point is x = 2.
And it is asked to find the area in the interval (2, 4).

We will use integration by parts.
