The angles in a triangle add up to 180 so one can calculate depending on the type of question or information given. For example;when one is given a scalene triangle, one can calculate the missing angle by equating all the angles to 180 and then find the missing one.
Add the two angles you have and then take 180 minus the number you got.
All (ALL) triangle add up to 180 degrees.
-----------------------------------------------------------
If you are given two, add the two angles up and subtract the sum by 180. That is the degree of that angle You can find the missing angles by one of 2 ways:
If you know the other 2 angles you can subtract them from 180.
There is a total of 180 degrees in a triangle and subtracting the other 2 gives you the third.
OR
If you only know the side lengths you can use Sin, Cos, Tan, etc. trigonometric functions to find it.
You use the SOHCAHTOA method for this.
Sin= Opposite side/Hypotenuse
Cos= Adjacent side/Hyoptenuse
Tan= Opposite side/Hypotenuse
so if you have angle x and you know the side opposite is 4 and the hypotenuse is 5
Sin X=4/5
using a protractor.
and vertical angles are called revolution angles
Right angle triangles have a 90 degree angle and 2 acute angles that add up tp 90 degrees.
Law of cosines
Yes, it can. And if you do the math, some basic trigonometry, you can calculate the angles in the triangle.
With a protractor or use trigonometry if you know its dimensions
One can learn how to calculate the angles of a triangle using sinc functions by enrolling in a pre-algebra, trigonometry, or algebra math class. These angles can be calculated by learning how to from a teacher proficient in mathematics and with one's own scientific calculator.
With a protractor or use trigonometry if you know its dimensions
That depends what you mean with "other angles". For example, if you are considering a triangle, the sum of all angles must be 180 degrees.
You use Lami's theorem wen you triangle of forces to calculate the sides of the triangle or the angles opposite to a side.
From geometry, we know that it is possible to calculate unknown lengths and angles of a triangle given particular information regarding the other angles and lengths of the sides of a triangle. For example, given beginning coordinates such as (x,y) in plane coordinates or the latitude and longitude, it is then possible to calculate new coordinates by measuring certain angles and distances (lengths of sides of a triangle).
The sum of all the angles in a triangle equals 180o. To find the missing angle, subtract the sum of the two known angles from 180o.ExampleTwo angles of a triangle are 35o and 62o. What is the third angle?Solution180o - (35o + 62o) =180o - 97o = 83o
The ratio can be used to calculate additional information about the sides or angles of a triangle.
The sum of all the interior angles of a triangle is 180 degrees while the sum of the exterior angles is 360. you can calculate for the measurements of the interior angles of a polygon by using the formula S=(n-2)(180) where n is the number of sides
If two angles in a triangle are congruent to two angles in another triangle, then the ______________ angles are also congruent.
