the verticales of triangle XYZ are X(-3,-6),Y(21,-6),and Z(21,4). What is the perimeter of the triangle​
andrezito [222]

Answer:

<h2>P = 60</h2>

Step-by-step explanation:

The formula of a distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

X(-3, -6), Y(21, -6). Substitute:

XY=\sqrt{21-(-3))^2+(-6-(-6))^2}=\sqrt{24^2+0^2}=\sqrt{24^2}=24

X(-3, -6), Z(21, 4). Substitute:

XZ=\sqrt{(21-(-3))^2+(4-(-6))^2}=\sqrt{24^2+10^2}=\sqrt{576+100}=\sqrt{676}=26

Y(21, -6), Z(21, 4). Substitute:

YZ=\sqrt{(21-21)^2+(4-(-6))^2}=\sqrt{0^2+10^2}=\sqrt{10^2}=10

The perimeter of the triangle XYZ:

P_{\triangle XYZ}=XY+XZ+YZ

Substitute:

P_{\triangle XYZ}=24+26+10=60
