the sine function is a many-to-one function and therefore has no inverse function.
However if the domain is restricted to -90° ≤ x ≤ 90°
Then the function is one-to-one for this domain
Thus, 
x is defined as the angle such that - π/2 ≤ x ≤ π/2
5π/6 is therefore outwith the domain
Expected value E(x) = 0.9994(150000 - 181) = 0.9994 x 149819 = $149,729.11
This was a quadratic formula
sin is the y value
here is me solving it
X+20+16=90
x=54
54+20+16=90
There’s a right angle and it’s marked as 90 degrees.
Answer:
3+16 divided by 4 is 4.75
4×7-2×6..... is5.33
168
