What is coordinate geometry?Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
The points are J(-7, 4), K(-4, 4), L(-2, 3), and M(-8, 3).
We know that distance between two points will be given as
[tex]\rm D= \sqrt{(x_2 - x_1 )^2 + (y_2 - y_1)^2}[/tex]
The distance between JK will be
[tex]JK = \sqrt{(-4+7)^2 + (0)^2 } = 3[/tex]
The distance between KL will be
[tex]KL = \sqrt{(-2+4)^2 + (3-4)^2 } = \sqrt5[/tex]
The distance between LM will be
[tex]LM = \sqrt{(-8+2)^2 + (0)^2 } = 6[/tex]
The distance between JK will be
[tex]MJ = \sqrt{(-7+8)^2 + (4-3)^2 } = \sqrt2[/tex]
Then the perimeter will be
Perimeter = JK + KL + LM + MJ
Perimeter = 3 + √5 + 6 + √2
Perimeter = 9 + √2 + √5

Answer:
v = [tex]\frac{7\sqrt{2} }{2}[/tex]
u = [tex]7[/tex]
Step-by-step explanation:
First, the angle on the far left is also 45 degrees.
So, v is equal to [tex]\frac{7\sqrt{2} }{2}[/tex] because this is a 45-45-90 triangle, so the sides opposite the 45-degree angles are congruent.
However, u is the side opposite the 90-degree angle, so it is equal to the other side value, multiplied by [tex]\sqrt{2}[/tex].
So, [tex]\frac{7\sqrt{2}}{2}*\sqrt{2}[/tex] is equal to:
