Typically, a point in a three-dimensional cartesian coordinate system is represented by which of the following a) (x,y,v) b) (w,x,y) c) x,y,z d) (x,y,z)

option D) (x,y,z)

Step-by-step explanation:

we know that

The three-dimensional Cartesian coordinate is defined by three axes at right angles to each other, forming a three dimensional space.

The three axes are labeled x ,y and z.

The x-axis is called abscissa

The  y-axis is called ordinate

The z-axis is called applicate

therefore

A point in a three-dimensional Cartesian coordinate is represented by (x,y,z)

<A=50

Step-by-step explanation:

85+x+55+x+50=180

2x+190=180

2x=180-190

2x=-10

x=-5

A=x+55

A=-5+55

A=50
