please answer fast and help me....​

Answer 1

Answer:

tan 9999

Step-by-step explanation:

is the answer

Answer 2

tan53 = cot(90-53) = cot37 = 1/tan37

cot45 = 1

cot30 = tan(90-30) = tan60 = 1/cot60

tan53×tan37 = 1/tan37 × tan37 = 1

tan25×cot25 = 1/cot25 × cot25 = 1

cot30×cot60 = 1/cot60 × cot60 = 1

Therefore,

tan 53 tan 37 + tan25 cot 25+ cot 45 +cot 30×cot 60

= 1 + 1 + 1 + 1 = 4
