The total sum of angles in any right triangle is 180 degrees.
The total sum of angles in the question would amount to 190 degrees and therefore no such right angled triangle is possible.

What are the kinds of angles in trigonometry?
adjacent opposite hypotenuse
Can you find the hypotenuse of a right triangle when only one side length is known and all three angles?
Yes. You will need to use trigonometry. sin (angle) = opposite/hypotenuse cos (angle) = adjacent/hypotenuse tan (angle) = opposite/adjacent
What is the equation for finding the sine and cosine and tangent of a triangle?
For finding the angles in a right angled triangle the ratios are: sine = opposite divided by the hypotenuse cosine = adjacent divided by the hypotenuse tangent = opposite divided by the adjacent
Real life examples of adjacent angles?
In a right angle triangle the adjacent angle is at the base of the hypotenuse and next to the right angle
How do you find the two shorter sides of a triangle when all you know if the hypotenuse and nothing else?
If it has an hypotenuse then it is a right angle triangle and if you know its angles then use trigonometry to find its other two sides.

How do you determine which is the adjacent side of a right triangle?
There are three sides, hypotenuse, opposite and adjacent. But the adjacent and opposite are not fixed sides: it depends on which of the two acute angles you are examining.For either of the non-right angles, the adjacent side is the one which forms the angle, along with the hypotenuse. For the given angle θ, the length of the adjacent side compared to the hypotenuse (adjacent/hypotenuse) is the cosine (cos θ).

What is the side adjacent to the forty degrees of a right triangle has a hypotenuse of 6 meters and one of its angles measure forty degrees?
The side adjacent to the forty degrees of a right triangle with a hypotenuse of 6 meters and one of its angles measuring forty degrees is: 4.6 meters.
How do you solve right triangles in Trigonometry?
you use the the 3 trigonometry functions , sin=opposite divided by hypotenuse cos=adjacent divided by hypotenuse tan=opposite divided by adjacent these are used to work out angles and side lengths in right angle triangles only!!! sine,cosine,tangent :)

If it has an hypotenuse then it is a right angle triangle and if you know its angles then use trigonometry to find its other two sides.
What is sine in trigonometry?
The sine of one of the acute angles in a right triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.
How do you find the side length of a right triangle if you have one side length and two angles?
You can use trigonometry: sin α = opposite/hypotenuse, cos α = adjacent/hypotenuse, tan α = sin α/ cos α and using the law of sines:a/sin a = b/sin b = c/sin c. From all these you can derive equations to help you solve your task. Also if you have two angles and a triangle you actually have three angles α + β + γ = 180 in a triangle
What's the equation to find the length of a hypotenuse of a triangle?
The basic equation for the hypotenuse of a right angled triangle is A squared plus B squared equals C squared. Where A and B are the two non hypotenuse sides and C is the hypotenuse. To find other lengths and angles of a triangle various functions in the branch of mathematics known as trigonometry is used.
How do you find the length of the hypotenuse?
In a right-angled triangle, the hypotenuse is the longest side, opposite the right-angle. There are two ways of finding the length of the hypotenuse using mathematics: Pythagoras' theorem or trigonometry, but for both you need either two other lengths or an angle. For Pythagoras' theorem, you need the other two lengths. The theorem is a2+b2=c2, or the square root of the sum of two angles squared, where c=the hypotenuse. Let's say that one length is 4.8cm and the other 4cm. 4.82+42=6.22. So, the answer is 6.2cm. If you have one side and one angle, use trigonometry. You will need a calculator for this. Each side of the right-angled triangle has a name corresponding to the positioning of the angle given. The opposite is the side opposite the given angle, the adjacent is the side with the right-angle and the given angle on it, and the hypotenuse is the longest side or the side opposite the right-angle. There are three formulas in trigonometry: sin, cos and tan. Sin is the opposite/hypotenuse; cos is the adjacent/hypotenuse; and tan is the opposite/adjacent. As we are trying to find the hypotenuse, we already have either the opposite or the adjacent, and one angle. Let's say that our angle is 50o and we have the adjacent side, and that is 4cm. So, we have the adjacent and want to know the hypotenuse. The formula with both the adjacent and the hypotenuse in is cos. So, Cos(50o)=4/x where x=hypotenuse. We can single out the x by swapping it with the Cos(50o), so x=4/Cos(50o) -> x=6.22289530744164. This is the length of the hypotenuse, and is more accurate that Pythagoras' theorem.
