Answer:
A computer network
Step-by-step explanation:
Answer:
A=28.27
Step-by-step explanation:
The value of
will be ![-\frac{3}{5}](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B5%7D)
<u><em>Explanation</em></u>
Given that,
According to the below diagram,
As,
is in quadrant III , so AB = -3 and BO = -4
Now according to the Pythagorean theorem.....
![AO^2= AB^2+BO^2\\ \\ AO^2= (-3)^2+(-4)^2\\ \\ AO^2= 9+16=25\\ \\ AO=\sqrt{25}=5](https://tex.z-dn.net/?f=AO%5E2%3D%20AB%5E2%2BBO%5E2%5C%5C%20%5C%5C%20AO%5E2%3D%20%28-3%29%5E2%2B%28-4%29%5E2%5C%5C%20%5C%5C%20AO%5E2%3D%209%2B16%3D25%5C%5C%20%5C%5C%20AO%3D%5Csqrt%7B25%7D%3D5)
Thus, ![sin(\theta)= \frac{opposite}{hypotenuse}=\frac{AB}{AO}= -\frac{3}{5}](https://tex.z-dn.net/?f=sin%28%5Ctheta%29%3D%20%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D%3D%5Cfrac%7BAB%7D%7BAO%7D%3D%20-%5Cfrac%7B3%7D%7B5%7D)
