Question

Solve : 13) if cosec theta =√5...

Answer 1

Answer:

If cosec theta= 13/5

as sin= 1/cosec= 5/13

cos = √1-sin^2 theta

= √1-(25/169

= √144/169= 12/13

tan = sin /cos= 5/13/(12/13)

= 5/12

Answer 2

Answer :

If cosec theta = √5 and theta is less than 90°, the value of cot theta - cos theta will be 2(√5 - 1)

Theta is less than 90°

cosec theta=√5/1(h/p)

cot theta-cos theta

=(2/1-2/√5)

=(2√5-2/√5)

=so,2(√5-1)...
