The sum of the angles is 180 degrees. So if the ratios are a, b and c then the angles are
180*a/(a+b+c), 180*b/(a+b+c) and 180*c/(a+b+c) degrees.

How do you find the length of the other two sides of a triangle when given a hypotenuse?
Unless you are given atleast 2 other angles, there is no way to find them out.
How do you find the angle of triangle if their sum and difference is given?
In plane Euclidean geometry there are 3 angles in any triangle that add up to 180 degrees and if given 2 angles the sum of the 2 angles minus 180 will give the measure of the 3rd angle
How do you find the area of a triangle if only the bases is given?
It is impossible, you need height or angles at least
How do you find the angles of a triangle only given the angle 38?
This is not sufficient information. The angles of a triangle add up to 180o and so all that can be deduced is that the remaining angles add up to 180o-38o which is 142o.
Can you find all sides of a right triangle given only two angles?
No. If you only know angles, you can't find any sides.Millions of triangles can all have the same angles. In fact, an infinite number of them can.
How do you find out the height of a triangle if only the 3 angles are given?
It is impossible to find a triangle if only angle measures are given (all similar triangles have the same angles).
How can you use ratios of the side lengths to find the angle measures of the acute angles in a right triangle?
By using trigonometry that is applicable to a right angle triangle.
What is the ratio used to find the tangent of a triangle In trigonometry what three common ratios are used to find the measures of the angles and sides of triangles?
financial ratio
How do you find the missing angle of a triangle if you are given two of the angles?
180 minus two known angles = unknown angle
How do you find the measure of an angle in a triangle?
Add together the given angles, or the angles you already know or have been given measures for, and then subtract the added numbers from 180 and that is you answer.
How do you find the length of the other two sides of a triangle when given a hypotenuse?
Unless you are given atleast 2 other angles, there is no way to find them out.
How can you find the angles of a right triangle with sides 20 21 and 29?
Because it's a right angle triangle use any of the trigonometrical ratios to find the two interior acute angles: tangent = opp/adj, sine = opp/hyp and cosine = adj/hyp The angles are to the nearest degree 46 and 44

What are the 3 trig ratios and how do they work?
A right angle triangle has three sides and three interior angles one of which is 90 degrees. The names of its sides are the adjacent the opposite and the hypotenuse and using the 3 trig ratios we can find the interior angles or lengths of the sides depending on the information given.Tangent angle = opposite/adjacentSine angle = opposite/hypotenuseCosine angle = adjacent/hypotenuseIf we are given the lengths of 2 sides we can work out the angles with the above ratios.If we are given a length and an angle we can work out the lengths of the other 2 sides by rearranging the above ratios.
How do you find the angles of a triangle only given the angle 38?
This is not sufficient information. The angles of a triangle add up to 180o and so all that can be deduced is that the remaining angles add up to 180o-38o which is 142o.
When do you use sin in geometry?
When you wish to measure certain aspects of angles. You could use it to find the ratios of sides of a triangle, or the area of a triangle or a segment of a circle. You could use it to study simple harmonic motion.
