The portuguese man o' war, physalia physalis, is a siphonophore, related to jellyfish. a small fish called the man-of-war fish is partially immune to the stinging cells of the siphonophore and can live among the tentacles. the man-of-war fish benefits from this shelter and does not affect the portuguese man o'war. what type of relationship is this, and why?

a. commensalism because one species benefits.
b. mutualism because both species benefit.
c. parasitism because one species is harmed.
d. predation because on species dies.

A because the fish benefits but the man of war is unaffected by it meaning it doesnt hurt or help therefore commensalism.

The value of x = 35.62

Therefore, option C) is true.

Step-by-step explanation:

Given

Ф = 58°

hypotenuse = 42

To determine:

x = ?

We know that the trigonometric ratio

sin Ф = opposite / hypotenuse

Here:

The opposite of Ф = xФ = 58°hypotenuse = 42

so substituting the value

sin Ф = opposite / hypotenuse

sin 58° = x / 42

x = 42 × sin 58°

  = 35.62

Thus, the value of x = 35.62

Therefore, option C) is true.
