यदि (A=2.4), (B=-1.8), और (C=5.1), तो (AB) और (AC) की लंबाइयों का अंतर क्या है?
If (A=2.4), (B=-1.8), and (C=5.1), what is the difference between lengths (AB) and (AC)?
Explanation opens after your attempt
A. (1.5)
Concept
(AB=|2.4-(-1.8)|=4.2) and (AC=|2.4-5.1|=2.7), so the difference is (1.5). Use absolute value for distance.
Why this answer is correct
The correct answer is A. (1.5). (AB=|2.4-(-1.8)|=4.2) and (AC=|2.4-5.1|=2.7), so the difference is (1.5). Use absolute value for distance.
Exam Tip
(AB=|2.4-(-1.8)|=4.2) और (AC=|2.4-5.1|=2.7), इसलिए अंतर (1.5) है। दूरी में निरपेक्ष मान लगाएँ।
