Tina observes the points on the plane of a paper. what is the minimum number of points required to make a plane

The minimum number of points required to make a plane is three.

Step-by-step explanation:

The minimum number of points required to make a plane is three. But the condition is that the three points must be non co linear.

Let us understand this with the help of a diagram. Let there are three points in xyz-plane which are not colinear. The coordinates of points are A(1,0,0),B(0,1,0) and C(0,0,1). From the figure, we have

x-intercept = 1

y-intercept = 1

z-intercept = 1

When we join these points we'' get a plane. The equation of the plane in intercept form is given by

Therefore, we can conclude that there should be three non colinear points to make a plane.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
