For each angle θ listed below, find the reference angle α, and then find sin θ. round sin θ to four decimal places, if necessary. ref. angle a sin θ θ = 132° ? ?

Answer with explanation:

It is given that

The Angle lies in Second Quadrant.

Formula to find reference Angle

→If Angle lies in first Quadrant

  then Reference Angle = The Angle given

→If Angle lies in Second Quadrant

  Then Reference Angle = 180° - Angle

→If Angle lies in third Quadrant

  then Reference Angle =  Angle - 180°

→If Angle lies in fourth Quadrant

  Then Reference Angle = 360° -Angle

Reference Angle

⇒sin 48°=0.7431448

Rounding to four decimal places

Sin 48°=0.7432

true
