Trigonometry

Trigonometry is the study of triangles and their properties

10 feet, and it is at a very dangerous angle.

Density = mass / volume

since earth is nearly spherical, Volume = (4/3)pi x r3

find volume, then divide this into the mass.

Trapezoid

It is the angle opposite the given side of a figure (<CAB has Vertex of A because it is the tip of the moutain, which is the highest point)

Yes

Sine of an angle (in a right triangle) is the side opposite of the angle divided by the hypotenuse.

pi is not an abbreviation. It is a letter of the Greek alphabet symbol that symbolises one particular ratio.

It can be any object that is above or below the horizontal from the perspective of a viewer.

They are all ratios for triangles found by dividing one side of a triangle by the others.

Ex: sine=opposite side/hypotenuse.

***

This is so for a right-angled triangle. Non-right-angle triangle dimensions can be calculated by trigonometry but require more complicated derived formulae.

use right triangle trig... sin (angle) = opposite side/hypotunese, cos (angle) = adjacent side/hypotunese, and tan (angle) = opposite side/ adjacent side

the egr valve is underneath the air filter housing. WARNING: there are multiple things to cause the EGR system to malfunction other than the valve (BPT valve, broken vaccum hose, solenoid, clogged ports, EGR temp sensor). A good diagnosis would be worth being wrong by just replacing the valve. Trust me, I used to work for a Nissan dealer

The side of a triangle that is opposite to 90 degree angle is called hypotenuse. The side that is opposite to the given angle (The angle that is under calculations) is called opposite.

The side that is adjacent with the given angle is called base.

X2 - 5X = 24

X2 - 5X - 24 = 0

(X - 8)(X + 3)

X = 8

----------------and

X = - 3

A complex number has a real part and imaginary part. In x+iy, the x is real and the iy is imaginary. In 3d, you can have x+iy+ik. Complex numbers produce amazing fractals.

A wise man said complex numbers are useless and to be avoided at all cost.

because i said they do !

the top viw of a triangular prism is a triangle

It depends on the college and since you have not bothered to specify which one, I cannot provide a more useful answer.

To prove that three points are colinear, pick two points and form the equation of the line they describe, and then see if the third point lies on that line.

Cot in trigonometry is the cotangent, which is cosine over sine, or x over y.

It actually all started when the bridge was invented a long time ago, and people had to figure out not only how tall and wide the bridge would have to be so it wouldn't fall down, but also the degrees of measurement of the bridge that corresponds to the length of the sides of the bridge so the bridge can say secure and not fall down. A lot of times this involved right triangle trigonometry, and sometimes complex trigonometry for curving triangles or triangles that don't have a right angle. When the airplane was invented, pilots needed to calculate the number of degrees it was going to take off from the ground compared to all of the angles and distances in which it turns so the airplane can fly safely. When churches were invented too, trigonometry became really popular so people could design perfect shapes, and we wouldn't be able to do this without the tools we have today. One we became familar with all of these shapes and inventions, trigonometry involving triangles, circles, 3-d figures, and angles and distances and how that relates to the speed of a movement object compared to how fast the moving object is going and the time it takes an object to go from one place to another and what direction the moving object is going became very popular. I hope I helped!
