Answer:
27
Step-by-step explanation:
note that tanx cotx = tanx × 
= 1
Given
tanx - cotx = 5 ( square both sides )
(tanx - cotx)² = 5² = 25 ← expand left side using FOIL
tan²x - 2tanxcotx + cot²x = 25
tan²x - 2 + cot²x = 25 ( add 2 to both sides )
tan²x + cot²x = 27
ANSWER: 2 3/7
EXPLANATION: First you find out how many 7s go into 17. If you put one seven in, you have 10, and if you put two, you have 3. So now you have 2 groups of seven and one 3/7. That's 2 and 3/7.
