If tan θ = 4/3, then (sin θ + cos θ) = ?
Given: tan θ = 4/3 = Perpendicular/Base
Therefore, (Hypotenuse)2 = (Perpendicular)2 + (Base)2
= 16 + 9
= 25
Therefore, hypotenuse = √25
= 5
Therefore sin θ = Perpendicular/Hypotenuse
= 4/5
Also, cos θ = Base/Hypotenuse
= 3/5
Thus, sin θ + cos θ = (4/5) + (3/5)
= 7/5
