Hope that helps!
On the problem you have given, the y ingercept shows the amount of time in hours it takes for the number of customers, so it would cross at 5 and represent 0 customers
by pythagorean formula, the last side is √(61)
by cos rule
cos A

A = 39.81
Y+x=98
y-x=22
I'm going to use elimination.
y+x=98
y-x=22
-----------
2y+0x=120 SIMPLIFY 2y=120 SIMPLIFY y=60.
Substitute that into either equation and you get y=60 and x=38
Have a nice day! :)
