*First you want to find out how much he makes a day
15x2=30
*so for 2 weeks he made $30 a day
*Obliviously there are 7 days a week so 7x2=14

Step-by-step explanation:
sinx = a/b
tanx= a/c
cosx= c/b
Step-by-step explanation:
AC+CB+BA=180
2x+23+3x-8+4x+1=180
9x+16=180
9x=180-16
9x=164
x=164/9
x=18.2
