E and F and B are your correct answers, 40/60 equals 2/3 and F is a automatic choice answer, divide the n/d for letter E By 2 and you get 2/3. B is also correct if you divide the n/d by 6, you get 2/3. Enjoy the lesson and happy studying:)
Using the law of sines,
sin80°/3.1 = sin∠QSR/2.4
∠QSR = sin^-1(2.4sin80°/3.1)
≈ 49.679°
∠SQR = 180° - 80° - 49.679° (angles in a triangle)
= 50.321°
sin50.321°/RS = sin80°/3.1
RS = (3.1sin50.321°/sin80°)
= 2.4 units (nearest tenth)
The length of line RS is 2.4 units.
The answer is line becuase a line is the only segment out fo the three types with arrows on eather end
hope this helps
<------> line
0----------0 segment
0------------> ray
