Question

From the following figure, find the values of:
(i) sin A
(ii) cos A
(mi) cot A
3
(iv) sec C
(v) cosec C
(V) tan C.
B​

Answer 1

Answer:

sin a=4/5

cos a- 3/5

cot a-3/4

sec c- 5/4

cosec c- 5/3

Tan c-3/4

Answer 2

Answer:

First of all, by Pythagoras theorem, we get AC = 5 units.

sin A = BC/ AC= 4/5

cos A = AB/AC = 3/5

cot A = AB/ BC = 3/4

sec C = AC/ BC = 5/4

cosec C = AC/AB = 5/3

tan C = AB/BC = 3/4
