Question

12.if If 3 tanA = 4 ,then( Sin A + Cos A) 10 is 14
28
30
none of above​

Answer 1

Let ABC is a right angle triangle

3tanA=4 ⇒tanA=34=ABBC

By using Pythagoras theorem

AC2=AB2+BC2

=(3)2+(4)2

=9+16=25

∴AC=25=5

sinA=HypotenuseOpposite side of∠A

=ACBC=54

∴cosA=HypotenuseAdjacent side of∠A

=ACAB=53

∴sinA=54 and cosA=54
