If x° 48′ is equal to 719π900 radians, then find the value of x.
यदि x° 48′, 719π900 रेडियन के बराबर है, तो x का मान ज्ञात कीजिए।
Answer और ExplanationAnswer and explanation
Answer: (B) 143
719π900 रेडियन = 719π900 × 180°π = 719°5 = 143.8°
0.8° = 0.8 × 60′ = 48′ (1° = 60′ यानी 60 मिनट)
इसलिए 719π900 रेडियन = 143° 48′
✓
x = 143।
719π900 radians = 719π900 × 180°π = 719°5 = 143.8°
0.8° = 0.8 × 60′ = 48′
So 719π900 radians = 143° 48′
✓
x = 143.
SMART APPROACH
48′ = 0.8° है। विकल्प जाँचें: (x + 0.8) × 5 = 719 होना चाहिए, यानी x + 0.8 = 143.8, तो x = 143।
48′ = 0.8°. Check the options: (x + 0.8) × 5 must equal 719, so x + 0.8 = 143.8 and x = 143.
