Question

In ∆ABC, if a=18, b=24, c=30 then find values of 1) cos A , 2) sin A and tan A​

Answer 1

Answer:

"Given lengths represent 'Pythagorean triplet' (18²+24²)=(30)²

a = 18, b = 24, c = 30

1] CosA = b/h = 24/30 = 4/5

2] SinA = p/h = 18/30 = 3/5

3] TanA = p/b = 18/24 = 3/4

Answer 2

Answer:

Step-by-step explanation:adj/hyp=18/30=3/5 Opp/hyp=24/30=4/5

Opp/adj=24/18=4/3
