Answer:
ST = 8.1
Step-by-step explanation:
To find the length of a segment of a straight line when given 2 points, we can use this formula:
[tex]\boxed{length=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}[/tex]
Given:
Then:
[tex]length=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]=\sqrt{(5-(-2))^2+(-4-0)^2}[/tex]
[tex]=\sqrt{7^2+(-4)^2}[/tex]
[tex]=\sqrt{65}[/tex]
[tex]\approx\bf8.1[/tex]
