I think you have to notice the pattern first. For every number of t-shirt sales, the cost is half of that. So, I think the expected number of t-shirt sales would be 60 for $30.

Will give brainly .Which statements are true regarding undefinable terms in geometry? Check all that apply.
babymother [125]

The true statements about terms in geometry that are undefinable are;

  • A point has no length or width
  • A point indicates a location on the coordinate plane
  • A line consists of an infinite set of points.
  • A plane consists of an infinite set of points.

<h3>How can the true statements be found?</h3>

Three undefinable terms in geometry are;

1) Point

2) Line

3) Plane

The above terms do not have a formal definition but they can be described based on their properties.

The other geometric terms are defined based on the above undefinable terms.

A point can be described as a location in space that is dimensionless and can be specified on the coordinate plane as an ordered pairs (x, y).

True statements about a point are therefore;

  • A point has no length or width
  • A point indicates a location on the coordinate plane

A line is infinitely long, that has no beginning or end. It has one dimension, with no thickness or height.

Given that a point is dimensionless, a line can be considered a set of points.

A true statement is therefore;

  • A line consists of an infinite set of points.

A plane is a two dimensional geometric figure that have infinite length and width.

An infinite set of lines that forms a two dimensional figure can be used to describe a plane.

The true statement with regards to a plane is therefore;

  • A plane consists of an infinite set of points.

Enter your answer and show all the steps that you use to solve this problem in the space provided. Find the values of x and y.
satela [25.4K]

Answer : The value of x and y is, 90^o and 43^oC

Step-by-step explanation :

First we have to calculate the angle B.

As we know that,

The given triangle is an isosceles triangle in which the angles opposite to equal sides are always equal.

Thus, \angle B=\angle C

Given : \angle C=47^o

\angle B=\angle C=47^o

\angle B=47^o

Now have to calculate the angle A.

As we know that the sum of interior angles of a triangle is equal to 180^o.

\angle A+\angle B+\angle C=180^o

\angle A+47^o+47^o=180^o

\angle A+94^o=180^o

\angle A=180^o-94^o

\angle A=86^o

Now we have to determine the angle y.

As we know that, line AD is an angle bisector. That means, it divides into two equal angles. So,

\angle y=\frac{\angle A}{2}

\angle y=\frac{86^o}{2}

\angle y=43^o

Now we have to determine the angle x.

As we know that the sum of interior angles of a triangle is equal to 180^o.

\angle y+\angle B+\angle x=180^o

43^oc+47^o+\angle x=180^o

\angle x+90^o=180^o

\angle x=180^o-90^o

\angle x=90^o

Thus, the value of x and y is, 90^o and 43^oC

The diagram shows , , and . Which statement can be proven true from the diagram?
tresset_1 [31]
What can be proven true in the diagram is the statement in letter C. angle CGB is complementary to angle AGD. It is because they both had the same vertex which is point G. Complementary angles are angles which are equal to 90 degrees wherein when you add both angles which are obviously 45 degrees, the sum is 90 degrees.
