C. 48
Tan=opposite:adjacent
Tan^-1(11/10) = 47.72
Answer:

Step-by-step explanation:

you can solve for the fractions first, but you have to give them a common denominator

which is in simplest form
then solve for the whole numbers
3-2=1
therefore, the answer is
z = 13/9?? i don't really know hope i helped
First, find the area for the kitchen floor: 16.5*15=247.5 squared feet
Then find the area for one tile: 0.5*0.5=0.25 squared feet
Finally, divide the mayor area between the minor: 247.5/0.25= 990 tiles.
Also you can do it in this another way:
First, divide length of the kitchen floor between the length of one tile: 16.5/0.5=33
Then, do the same for the height: 15/0.5=30
Finally multyply both results: 33*30= 990 tiles.
Answer:
y= 2/3x + 1.25
Step-by-step explanation:
I can't see the exact number but it's probably 1.25. Sorry if it's wrong :)
