Considering an inverse proportional relationship, you find k taking a point (x,y), and multiplying the values of x and y.
<h3>What is a proportional relationship?</h3>A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
For an inverse relationship, the function is:
.
Then:
k = xy.
Which means that to find k, you take a point (x,y), and multiply the values of x and y.

Answer:
m∠C = 90°
Step-by-step explanation:
Triangle BDC is a right triangle with the measure of angle D = 90°
By applying Cosine rule in the given triangle,
Since, Cosine of any angle in a right triangle is a ratio of Its adjacent side and Hypotenuse (Opposite side of the right angle)
CosC =
CosC =
CosC =
C = 28.955
C = 29°
Therefore, m∠C = 29° will be the answer.
