Question

find the value of tan25*/cot65*

Answer 1

Answer:

tan 25°/cot 65°

=> cot(90°- 25°)/cot 65°

=> cot 65°/cot 65°

=>1

Answer 2

Answer:

calculate the value of cot 65

Cot 65 = cot (90- 25) = tan 25

Since it involves 90 therefore tan will be changed to cot and 90- 25 remains in 1st quadrant therefore cot 65 will be written as tan 25.

Now tan 25 / cot 65. = tan 25/ tan 25 = 1

It's your answer

hope it helps
