Each floor of a hotel has r rooms. on 8 floors, there are a total of 256 rooms. write an equation to represent this situation.

Step-by-step explanation:

Given : Each floor of a hotel has r rooms.

Then, Total number of rooms in 8 floors will be:-

8 x Number of rooms in each floor

Total number of rooms in 8 floors = 8r                                             (1)

Also, On 8 floors, there are a total of 256 rooms.

⇒                    [from (1)]

Hence, the  equation represents the given situation will be :-

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

the equivalent expression are always the hardest ones but you look at the gcf also
