The total number of handshakes was 234.
- The first man shook hands with 12 other men.
- The second man shakes hands with 11 other men, as he had already shaken hands with the first man.
- Like-wise, the last man does not need to shake hands again as every man has already shaken hands with him in their respective turns.
- The number of handshakes among men is 0 + 1 + 2 + … + 12.
- The sum of "n" natural numbers = (n)(n+1)/2
- The number of handshakes among men is 12(13)/2.
- The number of handshakes among men is 78.
- Each man shakes hands with every woman except his spouse.
- Each man shakes hands with 12 other women.
- The number of handshakes between men and women is 13*12.
- The number of handshakes between men and women is 156.
- The total number of handshakes is 78 + 156.
- The total number of handshakes is 234.

A, B, C, and D are all correct in this situation.
The maximum force in Newtons that can be safely applied to the tiles is; 735 N
<h3>How to calculate the force from pressure?</h3>
We are given the dimensions of the rectangular floor as;
Length = 1.6 m
Width = 2.3 m
Now, we are told that the tile is only able to sustain a maximum pressure
of 200 Newtons per square metre (N/m²). The formula for pressure here is; Pressure = Force/Area
Thus;
Force = Pressure * Area
Maximum force = 200 * (1.6 * 2.3)
Maximum force = 736 N
Since the Pressure was approximated to the nearest 5 N/m², then;
Maximum pressure will be approximated downwards to 735 N/m²

Answer:
NO
Step-by-step explanation:
Thats an absolute value function, an absolute value function can not be negative
A because you all the values together with the value of a and set it equal to 180. Then whatever you get for “x” you find the values of each angle and see if they all add to 180 degrees.
