F(b)-F(a)/b-a
A=10 B= -2
F(a) =4 F(b)=17
17-4/-2-10
13/-12
Answer:
b ≈ 48.6°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin b = 
= 
, then
b = 
( ) ≈ 48.6° ( to 1 dec. place )

368 spaces now, why?
There are 22 spaces per row, and we know there are 8 rows, so thats 176 spaces last month,
we add 4 spaces to each row of 22, thats 26 spaces per row, 26 * 8 = 368 total spaces

Answer:
A, C
Step-by-step explanation:
The given ratio can be reduced by removing a factor of 2 from each element.
8 : 6 = 4 : 3 . . . . matches A
It can be put in other forms by multiplying each element by the same factor. Using a factor of 2 on the original ratio values, we get ...
8 : 6 = 16 : 12 . . matches C
__
Any ratio that doesn't reduce to the integer ratio 4 : 3 is not equivalent. The ratio with elements reversed (3:4) is not equivalent.
