Tan a=P/B so P=4 and B=3 and H=5 (by pythagorus theroem)
So value of Sin a =P/H
=4/5
Value of Cos a=B/H
=3/5
Sin a+ Cos a= 4/5+3/5
= 4+3/5
=7/5

Step-by-step explanation:
if 3tanA-4=0
then3 tan A = 4
then, tan A =4/3
if tan A = 4/3
then opposite side = 4
adjacent side =3
hypotenuse= 5
sin A = opposite side/hypotenuse
=4/5
cos A = adjacent side/opposite side
= 3/5
3sinA + 4cosA=3(4/5)+4(3/5)
12/5+12/5
24/5 or 4.8
