Question

if tan A=4/3 then the value of sin A+cos A is​

Answer 1

Answer:

sina+cos a= 7/5

Step-by-step explanation:

if tan a = 4/3  then first side= 4cm and second side = 3 cm so

hypotenuse^2 = 4^2+3^2= 16+9=25

hypotenuse = 5cm

so now

sin a = opposite side / hypotenuse =4/5

cos a = adjacent side / hypotenuse = 3/5

so , sina+cosa = 4/5 +3/5 = 7/5
