tan(x) = opposite / adjacent

the hypotenuse is the longest side of 10, so C and D are not correct.

Side b is adjacent to the 30° angle
Side 5 is opposite of the 30° angle

tan(30) = 5/b

In this exercise we want to calculate the value of angle B, so we have to:

Letter A

So knowing the tangent formula as:

[tex]tan(x) = opposite / adjacent[/tex]

Knowing some information given in the exercise such as:

  • the hypotenuse is the longest side of 10
  • Side b is adjacent to the 30° angle
  • Side 5 is opposite of the 30° angle

So we have:

[tex]tan(30)=5/b[/tex]
