Answer:
cos^(-1)(12/13) = 22.62°
Step-by-step explanation:
Inverse trig functions are used to find angles. I was taught SOH CAH TOA: sine = opposite/hypotenuse, cosine = adjacent / hypotenuse, tan = opposite / adjacent.
Here, we have an adjacent side length and the hypotenuse. So we use inverse cosine.
Answer:
560,317.460
Step-by-step explanation:
The computation of copies that have been sold is shown below:-
we assume the number of copies is x
So, the number of copies in the first month is
= 
As per the situation the number of sold copies is 35,300 so the equation will be



after solving the above equation we will get the number of copied that have been sold to date
= 560,317.460
I usually add x and divide by too and add y and divide by 2
1 1/3 = 4/3... 4/3 ÷2 —> 4/3 x 1/2= 2/3
4 2/3 = 14/3... 14/3 - 2/3 = 12/3= 4
