Statement.
(1). ∠1 is right angle & ∠2 is right angle

(2). ∠1 = ∠2

Reason
(1). Given

(2). Euclid’s Fourth Postulate states that all right angles are equal to one another.

Warning
This is assuming, that we only include Euclidean geometers.
This is because Euclidean geometry only recognise angles between straight lines.

So we have Non-Euclidean geometry for things that are not straight but this raises a question what is a straight line?

A general definition is (A curve is "straight' if tangent vectors stay tangent when parallel-transported along that curve)

What is the value of x?<br><br><br><br> Enter your answer in the box.
lubasha [3.4K]

Notice that based on the diagram, all of the sides of the triangle are the same length. (The dashes on the sides of the triangle show that the sides are of congruence.) This means that the triangle is an equilateral triangle. An important thing to note about equilateral triangles is that they all have angles of 60°. All angles in equivalent triangles are 60°.


This means that we can set 7x - 3 equal to 60 to solve for x:

7x - 3 = 60

  • Set up

7x = 63

  • Add 3 to both sides

x = 9

  • Divide both sides by 7

Our answer is x = 9.

Veronika [31]

Answer:

After one unit is sold, Becky will break-even.

Step-by-step explanation:

Giving the following information:

Fixed costs= $1

Unitary variable cost= $21

Selling price= $22

<u>The break-even point is the number of units required to cover the fixed costs after deducting from the selling price the variable components. At this point, net income is zero</u>.

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 1 / (22 - 21)

Break-even point in units= 1

After one unit is sold, Becky will break-even.
