Question
Find the possible values of x for which the angle (2𝑥 − 10) ° will be an acute angle.
Hint:
- Angles whose measure is more than 0 but less than 90 are called ‘acute angles’.
- Angles whose measure is more than 90 but less than 180 are called ‘obtuse angles’.
- Angles whose measure 90 are called ‘right angles’.
The correct answer is: 50
- Step-by-step explanation:
- Step 1:
As we know, angles whose measure less than 90o are acute angles.
∴ for (2x - 10)o to acute angle
0 < 2x - 10 < 90
0 + 10 < 2x < 90 + 10
10 < 2x < 100
< x < 
5 < x < 50
- Final Answer:
Hence, for all numbers more than 5 and less than 50 (2x -10) will be acute angles.
