The 6 in the hundreds place tells you the quotient is at least 100. The non-zero digits in the 1s and 10s places tell you the quotient is more than 100.
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 )
