Question

a) In a right angle triangle, if angle A is acute and cot A = 4/3

, find sin A, cos A and tan A

Answer 1

k square = L square + A square

= 3 square + 4 square

= (9)+(16)

= 25

k= 5

cot A = 4/3

cot A = adhar/lamb

sin A =lamb / kran

= 3/5

cos A = adhar/ kran

4/5

tan A = lamb / adhar

3/4
