Answer:
Correct Answer is B. 2.4 Units
Step-by-step explanation:
The missing picture in question is attached.
The Law of Sines is given as:
Where,
a,b,c are the length of sides of triangle
A,B,C are the angles between the two sides of triangle
According to the picture attached, we have ΔRQS,
Let,
r = 3.1 units
R = 80°
s = 2.4 units
S = S
q = RS
Q = Q
Using law of Sines:
°
Since, triangle is constitute of total 180°, hence,
∠Q + ∠R + ∠S = 180°
∠Q + 80 + 49.68 = 180
∠Q = 180 - 80 - 49.68
∠Q = 50.32°
To find line segment RS, again use law of sines:
