Question

if sin theta is equal to a/b,find the values of cos 90-theta and cosec theta​

Answer 1

Answer:

ans is a/b and a/a

Step-by-step explanation:

asin thetha =a/b

P/h=a/b

p=a h=b

by pythagores theorem

(h)square=(p)square+(b)square

(b)square=(a)square+(b)square

bsquare=asquare+(b) square

bsquare-bsquare=asquare

0=(a)square

a= base

cos90

P/H=a/b

cosec=p/b

a/a
