Arthur's dinner bill totaled $15.72, before sales tax and tip. Sales tax at the restaurant is 5.8%. After sales tax, he left a 15% tip. What was Arthur's total bill, including sales tax and tip?

I have the same question

Step-by-step explanation:

but instead the bill is 13.72, HELP

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
