To solve this problem you need to use
S(O)/(H) C(A)/(H)T(O)/(A)


S(O)/(H) means sin(x)=
(opposite)/(hypothenuse)

  • You have been given the angle of 25°, which lays directly opposite to the side x.
  • You have also been given the side length of 30, which is the hypothenuse.

Plug in the information into the equation, which leaves you with sin(25°)=
(x)/(30)

Multiply both sides by 30, then use your calculator to solve for 30× sin(25°)

The answer, rounded, is 12.68
