Question

if+tanA=4/3,then+(sinA++Cos+A)=?

Answer 1

Step-by-step explanation:

tan A =4/3

tanA=opposite/adjacent =4/3

so, according to Pythagoras theorem

(AB)square+(BC) square= (AC)square

so,AC=hypotenuse=5

sinA=opposite/hypotenuse=4/5

cosA=adjacent/hypotenuse=3/5

now,sinA+cosA=4/5+3/5=7/5
