Questions & Step-by-Step Solutions

Find the value of tan(45°).
Correct Answer: 1
  • Step 1: Understand what 'tan' means. 'Tan' stands for tangent, which is a function in trigonometry.
  • Step 2: Know that tangent of an angle in a right triangle is the ratio of the opposite side to the adjacent side.
  • Step 3: Recognize that for a 45° angle in a right triangle, the opposite and adjacent sides are equal.
  • Step 4: Since the opposite side and adjacent side are equal, their ratio (opposite/adjacent) is 1.
  • Step 5: Therefore, tan(45°) = 1.
  • Trigonometric Functions – Understanding the values of basic trigonometric functions, particularly the tangent function at standard angles.
