In a triangle, the angles are in the ratio of 2:3:5. What is the largest angle?
Category: Math · Difficulty: medium
Hint: Remember that the sum of angles in a triangle is always 180 degrees.
Answer
100 degrees
Explanation
Let the angles be 2x, 3x, and 5x. Then, 2x + 3x + 5x = 180, giving 10x = 180, so x = 18. The angles are 36, 54, and 90 degrees, making the largest angle 90 degrees.
This is a medium math riddle — a moderate challenge for most people. The answer is 100 degrees.
