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.
Answer:
Step-by-step explanation:
Slope formula= rise over run, or y2-y1 over x2-x1
y2=-4 y1=-18 x2=-7 x1=-7
-4-(-18)/-7-(7)
-22/-14 negative
1-7
3-21
5-35
7-49
