Total money Tammy has = $70
Money she is left with now = $19.54
Therefore, the money she used on coffee =

Answer:
1. Complimentary angles
2. 3x+20 = 10x-15: x = 5

Answer: 1250
Step-by-step explanation:
Let x be the cost before vat
13/100x = 162.50
x = 162.50 x 100/13
x = 162.50 / 2.13
x = 1250
Tan^-1 (tan x) = 42/25
x=tan^-1 42/25
x= 59.237 degrees.
