Answer:

solution:-

let A be the assumed angle so,

AB is hypotenuse, BC is perpendicular and AC is base.

Now, By using Pythagoras theorem,

h=√ (p^2+b^2)

=√(6^2+4^2)

=√(36+16)

=2√13

since we have, hypotenuse=2√13

Then,sin A=p/h = 6/(2√13) =3/√13

cos A=b/h = 4/(2√13) =2/√13

tan A=p/b = 6/4 =3/2
