Answer: There are 31 emails left in her inbox.
Step-by-step explanation:
Since we have given that
Number of emails in her inbox = 78
Number of emails she deleted = 47
We need to find the number of emails that are left in her inbox.
So, for left we would use "Subtraction operator"
So, Number of emails left in her inbox = Number of emails in her inbox - Number of emails she deleted.
Hence, there are 31 emails left in her inbox.

Answer and explanation:
Perpendicular lines are lines that meet at 90 degrees/ right angle.
The question seems to be incomplete but I will explain what perpendicular lines are in the context of lines lll and mmm, with some assumptions about the lines.
Assume that line III is 30mm long and line mmm is 25mm long, we say that line III is perpendicular to line mmm if line III meets line mmm at 90 degrees as we see in the diagram attached.
