Step-by-step explanation:

here is ur answer mate !!!

tan theta + cot theta = 5

squaring both sides

(tan theta + cot theta) ^2 = 25

tan square theta + cot square theta + 2 tan theta × cot theta = 25

(by using (a+b)^2=a^2 +b^2 + 2ab)

tan sq theta + cot sq theta + 2×1 = 25

(bcz tan theta × cot theta = 1)

tan sq theta + cot sq theta +2 =25

tan sq theta + cot sq theta = 25-2

tan sq theta + cot sq theta = 23
