Use Trigonometry.
Sine(Angle) = opposite/ hypotenuse => angle = Sin^(-1)[opposite/hypotenuse[
Cosine(angle) = adjacent /hypotenuse => angle = Cos^(-1)[adjacent/hypotenuse]
Tangent(angle) = opposite/adjacent => angle = Tan^(-1)[opposite/adjacent].
These trig. functions are often reduced to SOH,CAH,TOA.
Depending on your calculator the inverse buttons can be
Sin^(-1) or ArcSin
Cos^9-1) = ArcCos
Tan^(-1) = ArcTan
For example. The side lengths are 5,12,13
Hence
Sin(angle) = opposite/hypotenuse = 5/13
Angle = Sin^(-1) [ 5/13]
Angle = 22.61986495.... degrees.
or
Angle ~ 22.6 ( 1.d.p.).
Simillarly for the other angles, but make sure you use the correct Trig. Function.

How do you find the length represented the hypotenuse?
If it's a right angle triangle then use Pythagoras' theorem to find its various lengths.
How do you find out if a triangle is a right angle triangle given only the length of each side?
Measure 3 of any unit on one of the sides that you suppose have a right angle. Measure 4 of the same unit an the oher side you suppose has a right angle. the distance between the marks you made should mbe 5 if it is a right angle
What is the length of altitude drawn to the hypotenuse of a triangle with given sides of 7 and 21?
If it's a right angle triangle then use Pythagoras' theorem to find the 3rd side
How do you find the hypotenuse of a non right triangle?
By definition, the hypotenuse is the side opposite the right angle in a right angled triangle. Therefore, a hypotenuse does not exist as one of the three sides in a non-right angled triangle.
What is the formula to find the length of a right angle triangle?
For right-angled triangles ONLY, use Pythagoras. Ther Pythagorean Equation. is h^(2) = side(1)^(2) + side(2) ^(2). 'h' is the hypotenuse. It is the longest side, and ALWAYS opposite the right angle.
How do you find the length of the hypotenuse of a right triangle with the legs of 12 and 14?
By using Pythagoras; theorem for a right angle triangle.
How do you find the length of an hypotenuse?
If it's a right angle triangle then use Pythagoras' theorem.
How do you use the altitude to find the length of a right angle?
If 2 sides are known then use Pythagoras' theorem to find the 3rd side of a right angle triangle.
How do you use sine in math?
The sine function is used in trigonometric calculations when attempting to find missing side lengths of a right triangle. The sine of an angle in a triangle is equal to the length of the side opposite of that angle divided by the length of the hypotenuse of the triangle. Using this fact you can calculate the length of the hypotenuse if you know an angle measure and the length of one leg of the triangle. You can also calculate the length of a leg of the triangle if you know an angle measure and the length of the hypotenuse.
How do you find the length to a missing side of a right triangle?
Pythagorean Theorem: a2 + b2= c2 where c is the hypotenuse of a right triangle. Hypotenuse is the side of a right triangle opposite to the right angle.
If ABC is a right triangle if AC6 and CB9 what is AB?
Use Pythagoras' theorem for a right angle triangle to find the length of the 3rd side.
How do you find out if a triangle is a right triangle?
if the triangle has one right angle in it
How do you find the angle of a an right triangle?
The 90 degree angle in a right angle triangle is opposite its hypotenuse.
How do you find the length of a side of a triangle which is not a right angled triangle given two lengths and an angle?
Depending on which sides and angle are known you would use one of the trigonometry functions.
How do you find an angle within a non-right angled triangle when only given one side length?
You cannot find any angle, or either of the other two sides, in a non-right triangle, when given only one side.
What is the length of the hypontenuse y?
If it's a right angle triangle and you know its base and height then use Pythagoras' theorem to find the length of its hypotenuse.
