Answer: The equation is given by: 9- 1/3x = 7
Step-by-step explanation:
Let the number be denoted by x.
Now, we are given a word phrase as follows one-third of a number less than nine is equal to seven.
Now this word phrase could be mathematically expressed as a equation by: one third of x is 1/3 x
And this number less than 9 is given by :

9- 1/3x

Now, this number is equal to 7.
I.e. we finally have:
9- 1/3x = 7

For this case we will define the following:
A, B: are the values of the triangle angles
a, b: are the values of the lengths of the sides opposite the angles A, B.
We then have to use the law of the sine:
$\frac{sinB}{b} = \frac{sinA}{a}$
Clearing the angle B we have:
$sinB = \frac{sinA}{a}*b$
$B = arcsin(\frac{sinA}{a}*b)$
Substituting values we have:
$B = arcsin(\frac{sin113}{200}*134)$
$B = 38.08$
Answer:
the following is true:
A. angle B=38.08 degrees
