Find the following trigonometric values.

Mathematics
1 answer:
Alona [7]3 years ago
6 0

Answer:

\cos(150)\degree = -\frac{\sqrt{3}}{2}\\

\sin(150)\degree=\frac{1}{2}\\

Step-by-step explanation:

Formulae used:

cos (180°-θ) = -cos θ

sin (80°-θ) = sin θ

Therefore,

\cos(150)\degree = cos(180-30)\degree = -\cos(30)\degree = -\frac{\sqrt{3}}{2} \\\\\sin(150)\degree = sin(180-30)\degree = \sin(30)\degree = \frac{1}{2} \\\\

Tanzania [10]

Answer:

The decrease in the price will be $4032

The price of the next model is $31968

Step-by-step explanation:

The current model costs $36,000.

The next model of a sports car will cost 11.2% less than the current model

So, decrease in price =11.2\% \times 36000

                                   =\frac{11.2}{100} \times 36000

                                  =4032

So, the price of next model decrease by $4032

So, the price of the next model= 36000-4032 =31968

Hence the price of the next model is $31968
