The answer for the problem is 27.75
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
Your answer is

because the numbers raised to negative powers must be flipped over the divisor to become positive. Then, when multiplying 2 and z, you add their exponents.
Answer:
15
Step-by-step explanation:
The given equation is


When we multiply we obtain the equations:


We add both equations to obtain:

Divide both sides by -7 to get:
