By using Pythagoras theorem.. the angle is 53 degree(rounded to the nearest angle).. so x degree =53 degree
The first step for finding out whether or not this expression is equivalent to

is to reduce the fraction with

. You can begin to do this by dividing the terms with the same base by subtracting their exponents.

Subtract the exponents.

Now reduce the fraction with

by doing the same process. Since I just showed you how to do this,, I will skip over this.

Since we cannot simplify this expression any further,, your answer is going to be

,, which is not equivalent to

.
Let me know if you have any further questions.

Given:
Growth rate = 30% decrease
To find:
The growth factor associated with the given growth rate.
Solution:
The general exponential function is:


Where, a is the initial value, r is the growth rate in decimal and
is the growth factor.
It is given that the growth rate is 30% decrease. So,



Now,




Therefore, the growth factor is 0.7.
