or
divide both sides by 2
sinΘ = -
Since the sin ratio is negative then Θ is in third / fourth quadrants
Θ = (

related acute angle
Θ = ( π + ) =

Answer:
Step-by-step explanation:
Colored Fabric = 48 mm
White Fabric = 1.2 cm
<u><em>Ratio of white fabric to colored fabric is:</em></u>
48 mm : 1.2 cm
To express any ratio, we need to equalize the units ( 1 cm = 10 mm)
=> 48 mm : 12 mm
÷12 ÷12
=> 4 : 1
