How Do You Find the Sine of an Angle in a Right Triangle?

Find sin(A) in the right triangle given below

Summary

  1. In our ratio, "opp" stands for opposite and "hyp" stands for hypotenuse
  2. The opposite side is the side across from the angle
  3. The hypotenuse is the longest side of the right triangle
  4. The "≈" means approximately

Notes

    1. The sine of an angle is the length of the opposite side over the hypotenuse
    2. The opposite side is the side across from the angle
    3. The hypotenuse is the longest side of the right triangle
    1. The opposite side is the side across from the angle, which is 15
    2. The hypotenuse is the longest side of the right triangle, which is 17
