Why is a straight line 180 degrees?

Mathematics
1 answer:
a_sh-v [17]4 years ago
4 0
Think of a circle. We know it (and all circles) measure 360°. If you think about bisecting that circle, you would divide its 360° by 2, which results in 180°. The circle becomes a half-circle after being bisected, and its straight side (a straight angle) is 180°.

I've attached a diagram illustrating this.

What is a postulate?
zloy xaker [14]

Answer:

A statement, also known as an axiom, which is taken to be true without proof. Postulates are the basic structure from which lemmas and theorems are derived.

Step-by-step explanation:

The Addition Postulate: If you have one apple and Sally has one apple, when you both add the same quantity to your existing number of apples, you'll still have the same number of apples. Using algebra, the postulate states:

If x = y, then x + 4 = y + 4

The Subtraction Postulate: If you have ten apples and Sally has ten apples, when you both subtract the same quantity of apples from your existing number of apples, you'll still have the same number of apples.

If x = y, then x - 3 = y - 3

Without being repetitive, these same principles apply to both multiplication and division.

The Multiplication Postulate: If x = y, then x * 3 = y * 3

The Division Postulate: If x = y, then x / 7 = y / 7

Which graph represents the piecewise-defined function f(x) = StartLayout enlarged left-brace 1st Row 1st column negative 1.5 x +
PilotLPTM [1.2K]

Answer:

  • Option A or first option

Step-by-step explanation:

The function is

f(x) = \left \{ {{-1.5x + 3.5, x

Correct description is the first option with the exception of point (2,0), it should read (2, 0.5)

  • On a coordinate plane, a piecewise function has 2 lines. The first line has an open circle at (2, 0) and then goes up through (1, 2) with an arrow instead of an endpoint. The second line has a closed circle at (2, 6) and goes up through (3, 7) with an arrow instead of an endpoint.

The graph is attached
