Step-by-step explanation:
what is a rational number
Answer: 33
Step-by-step explanation: In the problem, you are given the figure with the following:
2x+3 and 3x+12
Method: Lets set this into an equation. Remember that straight lines add up to 180°.
2x+3+3x+12=180° Combine like terms.
5x+15=180°
5x=165°
x=33°
You can always plug in 33° in the expression that was set to make sure it does give you 180°.
Hope this helps.
I can only thin of a hot and miss method to do this . That is using Stirlings approximation for n!-
ln n! = approx n ln n - n
so if we try n = 60 this gives 4.2796 * 10^80
so we could try higher values:-
n = 65 gives an 89 digit number
n = 70 gives 98 digit number
n=71 gives me an memory error on my calculator!
Lets try an online calculator
Web2.0 calculator gives a 101 digit number or n=71
70 is your answer
