I think all you need to do is rise/run, in this case, 2420÷6050=0.4=40%
The answer is 23. you take .4 and times it by the first number, then times it by that number until you have 10 numbers. then add all of those numbers up
I don’t understand is there more to the question?
X is 20 degrees.
x+40=3x
2x=40
x=20
