A) 8
B) 10
C) 17
D) 19
Correct Answer: D
Solution :
(d): \[\Delta \,\Alpha \Beta C\cong \Delta \,PQR\Rightarrow \,\,\,\overline{AB}=\overline{PQ},\,\,\,\overline{BC}=\overline{QR};\,\,\overline{CA}=\overline{Rp}\]\[\Rightarrow \,\,2m+1=5\Rightarrow m=2;\,\,\,\,2p+2=8\Rightarrow p=3;\,\] \[\,7=2n-1\Rightarrow n=4\] \[\Rightarrow m+2n+3p=2+8+9=19\]You need to login to perform this action.
