Question

Points L, M, N are collinear such that d(L,M) = 9.5, d(M,N) = 7.8, find d(L,N) .​

Answer 1

Answer:

17.3

Step by step explanation:

collinear means minimum 3 points which lie in a straight line(refer to diagram in attachment)

line LN = length of LM +length of MN

=9.5+7.8

=17.3

Answer 2

LM=9.5

LM=9.5=>LM=MN+LN-----------(1)

LM=9.5=>LM=MN+LN-----------(1)MN=7.8

LM=9.5=>LM=MN+LN-----------(1)MN=7.8ᴘᴜᴛᴛɪɴɢ ᴛʜᴇ ᴠᴀʟᴜᴇ ɪɴ ᴇǫᴛɴ(1)

LM=9.5=>LM=MN+LN-----------(1)MN=7.8ᴘᴜᴛᴛɪɴɢ ᴛʜᴇ ᴠᴀʟᴜᴇ ɪɴ ᴇǫᴛɴ(1)=> 9.5=7.8+LN

LM=9.5=>LM=MN+LN-----------(1)MN=7.8ᴘᴜᴛᴛɪɴɢ ᴛʜᴇ ᴠᴀʟᴜᴇ ɪɴ ᴇǫᴛɴ(1)=> 9.5=7.8+LN =9.5-7.8

LM=9.5=>LM=MN+LN-----------(1)MN=7.8ᴘᴜᴛᴛɪɴɢ ᴛʜᴇ ᴠᴀʟᴜᴇ ɪɴ ᴇǫᴛɴ(1)=> 9.5=7.8+LN =9.5-7.8 = 1.7
