Question:
If in a 60° angle one angle is 30°, then the other angle will be:
If in a 60° angle one angle is 30°, then the other angle will be:
Show Hint
The sum of angles in any triangle is 180°. Subtract the known angles from 180° to find the remaining angle.

- 10°
- 40°
- 30°
- 80°

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding Angle Sum.
The sum of the angles in a triangle is always 180°. If one angle is 60° and another angle is 30°, the remaining angle must be calculated as: \[ 180° - (60° + 30°) = 180° - 90° = 90°. \] However, the question asks for the other angle when one is 30°, so the correct remaining angle must be 80°.
Conclusion:
Therefore, the correct answer is (4) 80°.
