Using relations in a right triangle, it is found that:
- Since x and y are complementary angles, we have that sin(xº) = cos(yº).
The relations in a right triangle are given as follows:
- The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.
- The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.
- The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.
The hypotenuse in this problem is given as follows:
h = 10.
The sine of x is:
The cosine of y is:
Since x and y are complementary angles, we have that sin(xº) = cos(yº).

Answer:
Average rate of change in amount of the element over 10 minutes is 0.15 per minute.
Step-by-step explanation:
Given question is incomplete; find the attachment of this question attached with the answer.
In this experiment change in amount of the element has been plotted on y-axis and duration (time) on x-axis.
Change in amount of the element during 0 to 10 minutes = 1.5 units
Now the duration of this change in amount = 10 minutes
Therefore, rate of change in amount of the element =
= 0.15 units per minute
