What are some uses of trigonometry in carpentry?
The Pythagorean Theorem: a^2+b^2=c^2, for checking squareness, a critical rule in carpentry. If two adjacent and perpendicular walls in a room are legs of a triangle, points a and b can be marked on each leg respectively and hypotenuse c measured with a tape measure (c) to confirm squareness or degree out of square. This can be used in many applications from framing to tiling. Most carpenters I've met use the 3-4-5 rule and don't even know what it's called!
How do you calculate sin inverse?
Sin or Sine is the ratio of the Opposite side Over The Hypoteneuse of any right angled triangle inverse sin or inverse sine ( they mean the same thing ) uses the same ratio to find an unknown angle and can be written as sin-1 so if you know two sides ( opposite and Hypoteneuse ) then you can work out the sin...then you can either use a calculator to determine the inverse ( or angle ) or you could look up the sin in a booklet of sin values and determine the angle Example : in the triangle ABC the line ab=4 ac = 5 and the angle abc =90 we could find the sin of the angle acb sinacb= opp/hyp = 4/5 = 0.8 to find sin-1 of 0.8 calcultor press 0.8 press inv button or on newer calculators the 2nd functon button then press the button marked sin the display should then display 53.1301....or 53 to 2 sig figures
When doing trigonometry for example the cosine rule how do you know which side is a which side is b and which side is c if none of them are marked on and neither are the angles?
It's possible that either the angles or sides are labeled according to length or size.
How do you find cosine on a scientific calculator?
First make sure the calculator is in 'Degree Mode'. Then press 'Cos' , followed by the angle in degrees, say '60' degrees, then press equals (=), and the answer should read '0.5'. NB If the calculator is in 'Radiuan Mode' Press 'Cos' followed by ' pi' divide '3' . Then equals (=) , again the answer should be '0.5'.
What are triangulation points?
Triangulation points, also known as survey markers or control points, are fixed locations on the Earth's surface used in surveying and mapping to determine precise geographical positions. These points are established through a process called triangulation, which involves measuring angles from known locations to calculate distances and positions. Triangulation points are crucial for creating accurate maps and are often marked with physical monuments or markers. They serve as reference points for various applications, including land surveying, construction, and navigation.
What states make up the German Triangle?

What is the tangent of a triangle?
In that triangle, one of the angles must be a right angle, and another one of the angles must be marked with or the measurement of the angle. Tangent is the ratio of opposite side over adjacent side. The opposite and adjacent sides are determined by the position of the marked angle.

What is the size of the angle in the shaded triangle marked by the arow?
It's 30o, no hang on, it's 28o...wait a minute, it's 57o. Hmmm...looks like my psychic abilities are failing me again: without the DIAGRAM I can't work it out (not can anyone else).

Why is a pkg of tofutti pops marked to have 12 pops inside package but only 11 is inside?
If a package of tofutti pops is marked as having 12 pops inside, the box should contain 12 pops. If there were only 11 tofutti pops inside the box, it is likely that there was a packaging error.
What does a letter j in a triangle crown and the letter f marked and under it marked withEP-11s?
The letter "J" in a triangle crown, along with the letter "F" marked with "EP-11s," likely refers to a specific brand or logo, possibly associated with a jewelry or design company. The triangle crown could symbolize quality or luxury, while "EP-11s" might denote a product model or series. However, without more context, it's challenging to determine the exact significance of these symbols.
