The proofing of the triangle is illustrated below.
<h3>How to illustrate the proof?</h3>
AB = c
BC = a
AC = b
h² = b² - x²
h² = a² - y²
a² - y² = b² - x²
a² = b² - x² + y²
Note that x = c - (c - x) = c
a² = b² - (-x)² + y²
a² = b² + c² + y²
Cos A = x/b
cos = adjacent/hypothenuse
x = bcosA
a² = b² + c² - 2bx
a² = b2 + c² - 2bccosA

5 holes =1 hour
10 = 6 hours
60 min in 1 hour
60x6=360
360min 360=/M
5/m=1h=10/m=M
bye the time ones donec its /M
1/10
C(h)=175+5h
C(h) is in dollars and h is in hours.
I believe it is 1.5 pounds each as 13 1/2=13.5
13.5/9=1.5
