Answer:
)
Step-by-step explanation:
From the diagram, .
The side of the triangle with length 11.9 is adjacent to the given angle.
We also know the hypotenuse to be 14.5 units.
We therefore use the cosine ratio to get;
We take the inverse cosine of both sides to get;
)
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:
