sin(0) is 0

A second of arc.

The word 'libero' is Italian. It comes from the Italian word that means free because the libero can switch in and out to play defense without using substitutions.

You cannot. Sine is a ratio, degrees are a unit of measurement for angular displacement. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.

yes

Not Real Hard in My opinion all that you really have to do is remember Formulas

1/3*8*4.6*height = 88

height = (3*88)/(8*4.6) = 7.174 meters rounded to 3 decimal places

cc is the volume unit.

1 cc = 1 milliliter

Cartesian coordinates are plotted on the Cartesian plane which consist of a horizontal x axis number line and a vertical y axis number line whereas both axes are perpendicular to each other and meet at right angles at the point of origin whose coordinates are at (0, 0)

Angles are measured in degrees, minutes and seconds

Base angles of an isosceles triangle are equal

Complementary angles add up to 90 degrees

Decagon is a 10 sided polygon whose inside angles add up to 1440 degrees

Exterior angles of any polygon add up to 360 degrees

F as a capital letter has equal corresponding angles

Greater than 0 but less than 90 is the measure of an acute angle

Hexagon is a 6 sided polygon whose interior angles add up to 720 degrees

Interior angles of any polygon: (n-2)*180 whereas 'n' is number of its sides

Joined line segments form angles at a point

K as a capital letter has angles that add up to 180 degrees on a straight line

L as a capital letter has a right angle

Measurements of angles can be done with a protractor

Nonagon is a 9 sided polygon whose interior angles amount to 1260 degrees

Obtuse angle is greater than 90 but less than 180 degrees

Perpendicular lines meet at right angles which is 90 degrees

Quarter of a turn is 90 degrees

Right angle triangle has a 90 degree angle and two acute angles

Supplementary angles add up to 180 degrees

Transversal line cutting through parallel lines creates various angles

Undecagon is an 11 sided polygon that has inside angles totalling 1620 degrees

Vertex is the point where two lines or more meet creating an angle

Whole turn is a complete revolution of 360 degrees

X as a capital letter has equal vertical opposite angles

Y as a capital letter has angles that add up to 360 degrees around a point

Z as a capital letter has equal alternate angles

A seven sided shape is called a heptagon or a septagon.......

The pole will not fit: The diagonal of the side with edge lengths of 3 m and 4 m is 5 m, from the Pythagorean theorem. The diagonal of a triangle perpendicular to the first named diagonal is sq rt (52 + 2.52) = 5.59, slightly shorter than the vaulting pole.

Cube, if the hexahedron is normal.

It is normally a parallel line parallel to the x or y axes on the Cartesian plane.

The sine curve is exactly the same as the cosine curve shifted pi/2 radians to the left

Yes, but it is called a hyberbolic trigonometric function

2x-5=3x+6

-5-6=3x-2x

-11=x

x=-11

It is pi radians.

In a problem which can be represented by a right angled triangle, the value of the cosine of an angle can be found by dividing the length of the side adjacent to the angle with the length of the hypotenuse, so if the shorter side was 16 units long and the hypotenuse was 25 units long the cosine of the angle between those two lines would be 16/25 = 64/100 = 0.064;these cosines can easily be found on even cheap hand calculators; it is more difficult and rather obsolete to look for them in a book of mathematical tables

This question doesn't mean anything. Explain more thoroughly.

Imagine a random triangle ABC. It will make it easier if you draw it with angle C at the top. The opposite side of angle A is labelled a, the opposite side of angle B is labelled b and the opposite side of angle C is labelled c. Draw the altitude (height) from angle C so that it is perpendicular (at 90 degrees) to side c.

Looking at this triangle, find expressions for the sines of angles A and B:

sinA = h/b

sinB = h/a

Rearrange these two equations in terms of h:

h = bsinA

h = asinB

As h = h, these equations can be set equal to each other and simplified to find the sine rule:

bsinA = asinB

sinA/a = sinB/b

If you expand on this way of working, you can also find that sinA/a = sinB/b = sinC/c. You have now proven the sine rule for all triangles!
