Question

If 12 sec A=13,find sin A and cot A​

Answer 1

Step-by-step explanation:

given that 12 SecA=13

secA= 13/12

wkt sec a = hyp/adj

hyp/adj =12/13

so by pythagoras therom

hyp2 = adj2+ opp2

(13)2 = (12)2+opp2

169 = 144+ opp2

169-144= opp2

opp=5

sinA = opp/hyp

sinA =5/13

cotA=adj/opp

cotA=13/12
