Find RA, 90: (2,5) given that point A is located at (-3, -3).
Anna71 [15]

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:

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

put the value in the formula:

\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\\
