Question

If Tan15°equal to cot75°= what find fast​

Answer 1

Answer:

if tan15°=cot75°

Step-by-step explanation:

tan15°=cot75°

therefore tan theta =cot(90°- theta)

so cot75°=cot75°=1

Answer 2

Answer:

Here tan15=cot(90-15)

So tan15=cot75

Now tan(45-30)=cot(45+30)

or tan(45-30).tan(45+30)=1

or tan15.(1+tan30)/(1-tan30)=1

we know tan30=1/root.3

putting this value we get

tan15=(root.3-1)/(root.3+1)

It is the answer
