Solving a linear system with 2 equations, 2 unknowns is like solving for the intersection of two lines. what is a similar way to picture the solution of 3 equations, 3 unknowns?

Three planes.

Step-by-step explanation:

In 2 dimensional system we have only 2 unknowns and these 2 unknown can be solve by the intersection of two lines.

Ex:In 2-D ,equation of lines

x + 2y = 4

y-x= 8

These two lines will give point.

Similarly in 3 dimensional we have 3  unknowns and these 3 unknown can be solve by the intersection of three lines.

Ex:In 3-D,equation of planes

x+2y+Z=8

x + y+6z=12

2x+ y+z = 20

step-by-step explanation:

its that because if it was in the pm it would be 1345

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
