The answer is Irrational. Hope this helps!
Answer: SECOND OPTION.
Step-by-step explanation:
You have the following formula given in the exercise, which is used to calculate gravitational potential energy.
You need to solve for the heigh "h".
Remembar that the Division property of Equality states that:
If , then
Therefore, you can divide both sides of the equation by in order to solve for "h".
Then, you get:
Notice that it matches with the second option.
Answer:
tanA =
Step-by-step explanation:
Before obtaining tanA we require to find EF
Using Pythagoras' identity in the right triangle.
EF² = DF² - DE² = ( )² - 7² = 60 - 49 = 11 ( take square root of both sides )
EF =
Then
tanA = = =
Your answer is n=2. thank me if this helped you. :)
