In a triangle, one angle is twice as large as another angle, and the third angle is 30 degrees less than the largest angle. What are the angles of the triangle?
Category: Math · Difficulty: hard
Hint: Use the properties of triangles to set up equations.
Answer
30, 60, 90
Explanation
Let the smallest angle be x. Then the other angles are 2x and (2x - 30). The equation x + 2x + (2x - 30) = 180 gives x = 30.
This is a hard math riddle — a tricky one that takes a little thought. The answer is 30, 60, 90.
