What basic trigonometric identity would you use to verify that sin x +1/ sin x=1 +csc x
SVETLANKA909090 [29]

Answer:  The correct option is (c). \csc x=\dfrac{1}{\sin x}.

Step-by-step explanation:  We are given to select the correct basic identity that we will use to verify the following:

\dfrac{\sin x+1}{\sin x}=1+\csc x.

We have

\dfrac{1+\sin x}{\sin x}\\\\\\=\dfrac{1}{\sin x}+\dfrac{\sin x}{\sin x}\\\\\\=1+\dfrac{1}{\sin x}.

In order to verify the given trigonometric equation, we must have

1+\dfrac{1}{\sin x}=1+\csc x\\\\\\\Rightarrow \dfrac{1}{\sin x}=\csc x\\\\\\\Rightarrow \csc x=\dfrac{1}{\sin x}.

Thus, the required identity that we will use is

\csc x=\dfrac{1}{\sin x}.

Option (c) is CORRECT.

A real estate broker's base salary is $18,000. She earns a 4% commission on total sales. How much must she sell to earn $55,000
VladimirAG [237]

The salary of the real estate broker = $18,000

Commission earned on total sales = 4% or 0.04

Total income earnings = $55,000

Let the total sales be = x

Equation becomes :

18000+0.04x=55000

0.04x=55000-18000

0.04x=37000

x=925000

Hence, the real estate broker must sell $925,000 worth of real estate to earn $55,000.
