Which of the following can be contained in a plane? a point a line a ray an angle

All of them.

Step-by-step explanation:

A plane extends infinitely in two dimensions. It has no thickness. An example of a plane is a coordinate plane. A plane is named by three points in the plane that are not on the same line. Here below we see the plane ABC.

A point has no dimensions.

A line or ray has one dimension and extends infinitely.

An angle has also dimension od length inradian.

So a plane can contain all of them because their dimensions is less the dimensions of the plane.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
