Answer:
b
Step-by-step explanation:
Using the trigonometric identities
cot x = 
and tan x = 
thus
+ tanΘ × cosΘ
= 
+ 
× cosΘ
= cosΘ × + sinΘ
= sinΘ + sinΘ
= 2sinΘ → b
Okay so make a coordinate plane, insert the numbers in the right place, then count what’s in between, you got this, I’ll totally help you if you didn’t get it.
Dang I’m dumb byeee use photo math it’s a app

Answer:
The elevator stops on the 19th floor.
Step-by-step explanation:
On the 16th floor, goes up 12 floors:

On the 28th floor, goes down 7 floors:
28 - 7 = 21
On the 21st floor, does up 3 floors:
21 + 3 = 24
On the 24th floor, goes down 5 floors:
24 - 5 = 19
