Answer the following.
Assoli18 [71]

Answer:

40000

Step-by-step explanation:

Simple interest (I) is calculated as

I = \frac{PRT}{100}

P is the amount borrowed , R is the interest and T the time in years

Here I = 2000 , R = 5 and T = 1 with P to be found , then

2000 = \frac{P(5)(1)}{100} ( multiply both sides by 100 )

5P = 200000 ( divide both sides by 5 )

P = 40000

From the trigonometry:

tan θ = (sin θ) / (cos θ)
cot θ = (cos θ) / (sin θ)

∴ tan θ + cot θ = (sin θ) / (cos θ)  +  (cos θ) / (sin θ)
  = [ sin² θ + cos² θ]/( sin θ cos θ) = 1 /( sin θ cos θ )


note :   sin² θ + cos² θ = 1
