Answer:4 gallons of water ... 30 plants
x gallons of water = ? ... 45 plants
If you would like to know how much water will it take to water 45 plants, you can calculate this using the following steps:
4 * 45 = x * 30
180 = 30 * x /30
x = 180 / 30
x = 6 gallons of water
Result: You will use 6 gallons of water to water 45 plants.

Answer:
See below ~
Step-by-step explanation:
Identities :
- cot x = cos x / sin x
- sin²x + cos²x = 1
Changing the Left Hand Side (LHS) :
- 1/cot x + cotx
- 1/(cos x / sin x) + cos x / sin x
- sin x / cos x + cos x / sin x
- Take (sin x)(cos x) as the LCM (Least Common Multiple)
- sin x (sin x) + cos x (cos x) / (sin x) (cos x)
- sin²x + cos²x / cos x sin x
- 1/cos x sin x
- Equal to the RHS
