Answer:
(D) 
Step-by-step explanation:
Given: In triangle ABC, a=9, c=5 and ∠B=120°.
To find: The value of 
.
solution: It is given that In triangle ABC, a=9, c=5 and ∠B=120°.
Now, using the law of cosines, we get
Substituting the given values, we get
which is the required value of .
Therefore, option D is correct.

How to find the algebraic expression that matches the graph?</h3>
On the graph, we can see an absolute value equation, which opens downwards, and passes through the points (1, 0) and (0,1).
The general absolute value equation is:
y = a*|x - b| + c
Because the vertex is at the point (0, 1), we know that:
b = 0, c = 1
Replacing that we get:
y = a*|x| + 1
Now, this must be zero when we evaluate in x = 1, then:
0 = a*|1| + 1
a = -1
Then the graphed equation is:
y = -|x| + 1
