Answer:
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 )
Answer:
Step-by-step explanation:
8x^2 - 8x + 2 - 5 + x.....combine like terms
8x^2 - 7x - 3 <=== g = 7 and h = 3
