Answer:
Step-by-step explanation:
given that,
5 sinA = 4
sinA = 4/5
sinA = opposite side to A / hypotenuse
then,
we have to find adjacent side by using pythagoras theorem.
=
-
let take adjacent side square as shortcut ""
=
A.S = ADJACENT SIDE TO A
secA = hypotenuse/adjacent side to A
secA = 5/3.
cotA = adjacent side to A/opposite side to A
cotA = 3/4
Hence,
(i) secA = 5/3
(ii)cotA = 3/4
