<span>If you plot these points, you can probably see where the missing square corner is.
But you might also notice that a square's sides are equal length. Between the first two coordinate pairs, the only thing that changes is the y value, from 5 to 2, or a change of 3. Between the 2nd two coordinate pairs, only the x value changes, from -5 to -2, or a change of 3. So it looks like the sides are 3 units long.
The fourth coordinate should be 3 units away on the x coordinate from one "neighbor" and 3 units away on the y coordinate from its other neighbor. But it really would help to sketch it out so you don't get mixed up.

Answer:
A: 10.9
Step-by-step explanation: -2.3 is 2.3 away from zero then add the length from zero to the postive number which in this case is 8.6, therefore the equation is 2.3 + 8.6 = 10.9
Expression: 8m+10m+10m+18m
Perimeter: 46
Step-by-step explanation:
step 1. sinA = 5/8
step 2. A = sin^(-1)(5/8) = 38.68°
