Answer:
D=25 units
Step-by-step explanation:
Distance Between Points In The Plane
Given two points P(a,b) T(c,d), the distance between PQ is given by
[tex]D=\sqrt{(c-a)^2+(d-b)^2}[/tex]
The given points are P(-10,15) and T(15,15). We can see they have the same value of y, so the line between them is horizontal. The distance can be easier calculated by just subtracting the values of their x-coordinates, but let's follow the formula
[tex]D=\sqrt{(15-(-10))^2+(15-15)^2}[/tex]
[tex]D=\sqrt{25^2+0^2}[/tex]
D=25
