Answer 1

Answer:

see this attachment ☺️☺️☺️☺️

Answer 2

tan A = 4/3

we know that,

tan A = opposite side / adjacent side

we get,

opposite side= 4

adjacent side = 3

and by Pythagoras theorem

hypotenuse = 5

now,

as we know that,

sin a = opposite side/ hypotenuse

= 4 /5

also,

cos a = adjacent side / hypotenuse

= 3/5

it will definitely help u....
