Answer:
A rate of change is a rate that describes how one quantity changes in relation to another quantity. If x is the independent variable and y is the dependent variable, then. rate of change=change in y change in x.
Step-by-step explanation:
Well,you can use the pythagorean theorem,which is a^2+b^2=c^2 to solve for x.
Ans = 2 move 8x to other side and 4 to other side
For this case we will define the following:
A, B: are the values of the triangle angles
a, b: are the values of the lengths of the sides opposite the angles A, B.
We then have to use the law of the sine:

Clearing the angle B we have:

Substituting values we have:
Answer:
the following is true:
A. angle B=38.08 degrees
