Answer:
θ lies in 1st & 4th Quadrant
Step-by-step explanation:
If sec theta +tan theta= 5 ,find the quadrant in which theta lies and find the value of sin theta.
Secθ + tanθ = 5
=> 1/Cosθ + Sinθ/Cosθ = 5
=> 1 + Sinθ = 5Cosθ
Sinθ lies between - 1 & 1
=> 1 + Sinθ lies between 0 & 2
=> Cosθ is always + ve
Cosθ is + ve in 1st & 4th Quadrant
=> θ lies in 1st & 4th Quadrant
