2) Use the law of sines to find the length of SR<br> sin⁡(A)/a=sin⁡(B)/b=sin⁡(C)/c

NeTakaya

Answer:

take 28 degree as reference angle

using sine angle

sin28=p/h

0.46=10/h

0.46h=10

h=10/0.46

h=21.73

therefore hypotenuse =21.73

again using sine rule

take 25 degree as reference angle

sin 25=p/h

0.42=SR/21.73

0.42*21.73=SR

9.12=SR

9.1=SR

Working independently at the same constant rate, 9 machines can fill an order in 20 hours. How many of these machines, working i

Katena32 [7]

Answer: 4 machines

Step-by-step explanation:

In the given situation, the number of machines is inversely proportional to the time taken by them.

Given : 9 machines can fill an order in 20 hours.

Let n be the number of machines required to fill the same order in 45 hours.

Then , we have the following inverse variation equation:-

$n\times 45=9\times20\\\\\Rightarrow\ n=\dfrac{9\times20}{45}=4$

Hence, the 4 machines would be needed to fill the same order in 45 hours.
