Answer 2

Answer:

tan A =3/4=PERPENDICULAR/BASE

AB=4;BC=3

then in triangle by Pythagoras theorem

(AC)^2=(AB)^2+(BC)^2

(AC)^2=(4)^2+(3)^2

(AC)^2=16+9

(AC)^2=25

AC=5=HYPOTENUSE

sin A=Perpendicular/hypotenuse

sin A=3/5

cos A=Base/hypotenuse

cos A=4/5

1/sin A=1 / 3/5

1/cos A=1 / 4/5

1/sin A+1/cos A

=1 / 3/5+1 / 4/5

=5/3+5/4

=20+15/12

=35/12
