Question

(tan 25°/
cot 25°)^2
+
+ 2 tan 18° tan 45º tan 72°
​

Answer 1

Answer:

and tan(90-x)= cot x hence, ( tan25°÷cosec65°)^2 +(cot25°÷sec65°)^2 +2 ( tan18°×tan45°×tan72°) = 3 answer

Answer 2

ANSWER

value of tan 25° = 0.46

value of cot 25° = 3.73

value of tan 18° = 0.32

value of tan 45° = 1

value of tan 72° = 3.07

I have given you the value,

now find out the value by own.
