Question

plz answer me guys ​

Answer 1

Answer:

tan 23° = cot(90°-23°) = cot 67°

So,

cosec^2 67° - cot^2 67° = 1

since,

cosec^2 A - cot^2 A = 1

identically for any Angle A

Hope this helps you !

Answer 2

Answer:

options D is the right answer of this question

Step-by-step explanation:

$\csc(67) = \csc(90 - 23) \\ \csc(67) = \sec(23) \\ { \csc}^{2}23 - { \tan }^{2} 23 + 1 \\ { \sec}^{2} 23 - { \tan}^{2}23 + 1 \\ 1 + 1 = 2$

Hope its help you❤
