Question

If the d.rs of a line are $\sqrt{3},1,2\sqrt{3}$ then the sum of the d.cs of that line is...

• A. $2\sqrt{3}+1$
• B. $\frac{3\sqrt{3}+1}{4}$
• C. $2\sqrt{3}+2$
• D. $\frac{3\sqrt{3}+2}{4}$

Answer 1

Answer: (B)

D.c s of line are $\frac{\sqrt{3}}{4},\frac{1}{4},\frac{2\sqrt{3}}{4}$
D.r’s of line are $\sqrt{3}+1+2\sqrt{3}=3\sqrt{3}+1$
