Geometry and Trigonometry practice question
The measures of the two acute angles of a right triangle are x° and 2x°. What is the value of x?
Answer: 30
The acute angles of a right triangle sum to 90°: x + 2x = 90 → x = 30.
Common wrong answers
- If you answered 45
- 45 assumes the two acute angles are equal.
- If you answered 60
- 60 is the larger acute angle, 2x.
- If you answered 90
- 90 is the right angle.
