Questions & Step-by-Step Solutions

In a right triangle, if one angle is 30 degrees, what is the ratio of the lengths of the sides opposite to the 30 degrees and 60 degrees?
  • Step 1: Understand that a right triangle has one angle that is 90 degrees.
  • Step 2: Recognize that if one angle is 30 degrees, the other non-right angle must be 60 degrees (since 30 + 60 + 90 = 180).
  • Step 3: Identify that this triangle is a special type called a 30-60-90 triangle.
  • Step 4: Learn the properties of a 30-60-90 triangle: the side opposite the 30-degree angle is the shortest and is often labeled as '1'.
  • Step 5: The side opposite the 60-degree angle is longer and is equal to '√3' times the length of the side opposite the 30-degree angle.
  • Step 6: Therefore, the ratio of the lengths of the sides opposite the 30 degrees and 60 degrees is 1:√3.
