Answer:
Ordered
Step-by-step explanation:
The ordered pair is the location of a point on the coordinate plane and contains the x coordinate and y coordinate
An ordered pair tells you the location of a point by relating the point's location along the x-axis (the first value of the ordered pair) and along the y-axis (the second value of the ordered pair). In an ordered pair, such as (x, y), the first value is called the x-coordinate and the second value is the y-coordinate.

Step-by-step explanation:
The largest angle is opposite to the largest side.
Since the largest side is BC, the largest angle is A.
<u>Work out the angle measure using the law of cosines:</u>
- cos ∠A = (b² + c² - a²)/(2bc)
- cos ∠A = (3² + 7² - 8²)/(2*3*7)
- cos ∠A = -0.14286
- m∠A = arccos (-0.14286)
- m∠A = 98.2°
let's first notice the distance of LM, is a vertical line, so we can just do a plain subtraction, -1.6 -(-0.4) => -1.6 +0.4 => -1.2 and the distance is just |-1.2| or 1.2.
let's check KJ, another vertica line, -1.7 - (-0.5) => -1.7 + 0.5 => -1.2 => |-1.2| = > 1.2.
so LM = KJ, and both are vertical, meaning we have a parallelogram, which means KL = JM.
so let's just find say... KL and her twin will be the same.

![\bf KL=\sqrt{[-0.7-(-0.5)]^2+[-0.4-(-1.7)]^2} \\\\\\ KL=\sqrt{(-0.7+0.5)^2+(-0.4+1.7)^2}\implies KL=\sqrt{(-0.2)^2+1.3^2} \\\\\\ KL=\sqrt{0.04+1.69}\implies KL=\sqrt{1.73}\implies KL\approx 1.315 \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \stackrel{\textit{perimeter}}{\stackrel{LM}{1.2}+\stackrel{KJ}{1.2}+\stackrel{KL}{1.315}+\stackrel{JM}{1.315}}\implies 5.03](https://tex.z-dn.net/?f=%5Cbf%20KL%3D%5Csqrt%7B%5B-0.7-%28-0.5%29%5D%5E2%2B%5B-0.4-%28-1.7%29%5D%5E2%7D%0A%5C%5C%5C%5C%5C%5C%0AKL%3D%5Csqrt%7B%28-0.7%2B0.5%29%5E2%2B%28-0.4%2B1.7%29%5E2%7D%5Cimplies%20KL%3D%5Csqrt%7B%28-0.2%29%5E2%2B1.3%5E2%7D%0A%5C%5C%5C%5C%5C%5C%0AKL%3D%5Csqrt%7B0.04%2B1.69%7D%5Cimplies%20KL%3D%5Csqrt%7B1.73%7D%5Cimplies%20KL%5Capprox%201.315%0A%5C%5C%5C%5C%5B-0.35em%5D%0A%5Crule%7B34em%7D%7B0.25pt%7D%5C%5C%5C%5C%0A%5Cstackrel%7B%5Ctextit%7Bperimeter%7D%7D%7B%5Cstackrel%7BLM%7D%7B1.2%7D%2B%5Cstackrel%7BKJ%7D%7B1.2%7D%2B%5Cstackrel%7BKL%7D%7B1.315%7D%2B%5Cstackrel%7BJM%7D%7B1.315%7D%7D%5Cimplies%205.03)
