D

Step-by-step explanation:

Using the Sine rule in Δ QRS , that is

= , that is

= ( cross- multiply )

12× sinQ = 15 × sin50.1° ( divide both sides by 12 )

sinQ = , thus

Q = ( ) ≈ 73.5° ( to the nearest tenth )

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
