Ok so first we need to work out the vertical line in the middle (ab) using Pythagoras
Square root(7.5^2+4.9^2) to get 8.958794562
Now we know the length of the line ab so we can work out x using trigonometry
Since line ab is opposite the angle and x is adjacent (or not the hypotenuse the slope) the tan rule is used which is tan(0)=o/a
So tan(55.8)=8.9587../a
*a. *a
/tan(55.8). /tan(55.8)
a=8.9587../tan(55.8)
a=6.088390497
a=6.09
x=6.09
Answer:

Step-by-step explanation:
He will get 12 issues too. Since he spent 15 dollars in total you would divide that by 1.50 to see how many he actually purchased and it comes out to 10 meaning that he got 10 issues with the money. Now he got two free issues so you would add them to the ones he purchased, so 10 + 2 which would equal 12. So in total he got 12 issues. I hope that helps and wasn't confusing.
Number 19 I think is if you add the awnser to one of the numbers you where subtracting and you get the other number you where subtracting you are right like...
Lets say you had the problem 3-2 which is obviously 1 but if you did 2+1 it's 3 so that's how you check.
