Question:
Find the value of: sin²30° + cos²60° + tan²45°
मान ज्ञात करें: sin²30° + cos²60° + tan²45°
Options:
- a) 1.5
- b) 2
- c) 2.5
- d) 3
- a) 1.5
- b) 2
- c) 2.5
- d) 3
correct answer : c)
Explanation:
sin30=½→¼. cos60=½→¼. tan45=1→1. Sum=¼+¼+1=1.5. Wait: ¼+¼+1=1.5 not 2.5. Answer=a. Actually let me recompute: 0.25+0.25+1=1.5.
sin²30=¼, cos²60=¼, tan²45=1। योग=1.5।
