Question

If SinA=45/53, find the value of TanA and CosA​

Answer 1

Answer:

cos A = 28/53. tanA=45/28

Step-by-step explanation:

sin A = 45/53 = opp./hyp.

(hyp)^2 = (opp)^2+(adj)^2

53^2 = 45^2 + (adj)^2

(adj)^2 = 2809 - 2025

= 784

adj. = √784 = 28

Cos A = adj./hyp.

= 28/53

Tan A = opp./adj.

= 45/28
