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} \\\\

mr Goodwill [35]

Given:

A sum of money is divided between A,B and C in the ratio 9:8:7.

Total sum is 480.

To find:

The part of money A get.

Solution:

Let A, B and C get 9x, 8x and 7x respectively.

Total sum is 480.

9x+8x+7x=480

24x=480

Divide both sides by 24.

x=\dfrac{480}{24}

x=20

Now,

A\ get =9x

A\ get =9(20)

A\ get =180

Therefore, amount received by A is 180.
