Answer:
7.7142
Step-by-step explanation:
hi
4 entries are 24 so one entry is 24/4 = 6
so 7 friends pay 6*7 = 42

We effectively rewrite the equation as

In order for the LHS to be defined, we need to restrict
, or
. Now, the LHS will vanish when the numerator is 0, which happens for

This value is indeed smaller than 4, so the solution is
.
-4
Both of those angles should be measured 112 degrees so -4+116=112
An equiavalent expression for 40+36 can be:
46+30
50+26
etc.
As long as the expression equals 76, it is correct
hope this helps
