The total length of her drive is 83 miles.
If 21 miles=1/3 of her drive, then multiply 21 by 3, to figure out 3/3 of her drive.
There are mainly six trigonometric functions for right angle triangle which are
- sinФ
- cosФ
- tanФ
- cosecФ
- secФ
- cotФ
All of these can be expressed in the form of sinФ and cosФ as following:
- sinФ = sinФ
- cosФ = cosФ
- tanФ = sinФ/cosФ
- cosecФ = 1/sinФ
- secФ = 1/cosФ
- cotФ = cosФ/sinФ
This angle Ф is shown in the attached drawing in a right angle triangle drawn within a circle which is the given angle. Right angle is mentioned as "90".
Parallel lines have equal slopes.
Step-by-step explanation:
We can rewrite the given equation as

As a check, let's multiply out the factors:


and this is our original equation.
All real numbers is the answer
