Answer:
30%
This is the only way I know this would make sense
Step-by-step explanation:
40+20+10=70
100-70=30
30%
Answer:
1. less than 0
2. negative
3. an infinite number of
Step-by-step explanation:
Combine like terms to get 11=-11k-22 then add -22 to both sides to get 33=-11k. then divide by -11. so k=-3
Use the Pythagorean theorem:
30^2 + 40^2 = X^2
900+ 1600 = x^2
X^2 = 2500
x = √2500
x = 50
The answer is 50 feet.
Always try to find a way to convert cotx, secx, cscx, and tanx into cosx and sinx
cotx (1/secx) = (1/sinx) - sinx
(cosx/sinx) (cosx) = (1/sinx) - sinx
cos²x / sinx = (1- sin²x)/sinx
cos²x = 1 - sin²x
sin²x + cos²x = 1
