Answer:
The value of RA is " 9.43".
Step-by-step explanation:
In the given question there is some typing mistake so, the points are:
R =(2, 5)
A= (-3, -3)
Find:
RA= ? where it is a distance (D).
Formula:
[tex]D= \sqrt{(x_2-x_1)^2+ (y_2-y_1)^2} \\\\\ compare \ the \ value \\\\x_1 = 2\\y_1=5\\x_2=-3\\y_2= -3[/tex]
put the value in the formula:
[tex]\Rightarrow D =\sqrt{(-3-2)^2+(-3-5)^2} \\\\\Rightarrow D =\sqrt{(-5)^2+(-8)^2} \\\\\Rightarrow D =\sqrt{25+64} \\\\\Rightarrow D =\sqrt{89} \\\\\Rightarrow D = 9.43\\[/tex]
