What is the formula to find hypotenuse of a right triangle with 2 angles given?

Depending on which two angles you are talking about (all angles are given if it is a right triangle with 2 other angles given) you can use simple Trig functions to find the hypotenuse.
For instance, you have a triangle with sides a, b, c.
a=3
b=4
c=hypotenuse
You can have either one given and the other one a mystery it does not matter. What does matter is which angle is given. Probably one other than the 90 degree angle in all right triangles.
For this instance pretend we didn't have (b) and we only have (a).
In between the angle(a,c) we have approx. 37 degrees.
If you input that into the reciprocal of sin you will get 1/(sin37) = csc37 = 1.661 or approx 1.666 repeating.
Multiply that number by your (a) since csc (cosecant) is your hypotenuse (c) divided by your other length included with the angle (a). Doing so will seclude the hypotenuse to one side of the equation, therefore giving you the answer.
If you multiply 1.666 by three you get 5, which is what you get if you take the root of 32 + 42.

Does sohcahtoa work on a 90 degree angle I have a right triangle with a hypotenuse of 1m no other sides or angles were provided?
No. Given a triangle with only the right angle and the hypotenuse, you cannot calculate the other sides nor the other angles.
When you use the Distance Formula you are building a triangle whose hypotenuse goes between two given points?
right triangle
How do you find the height of a triangle given the hypotenuse?
Providing it's a right angle triangle the formula is: hypotenuse2-base2 = height2
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 area of a 90 degree triangle with hypotenuse only?
The hypotenuse only is not sufficient to determine the area of a right triangle, unless the triangle is stated to be isosceles, or there is some other information that allows determination of the length of a side in addition to the hypotenuse. The area of a right triangle with a given hypotenuse only approaches zero as one of the two acute angles approaches zero degrees.

What is the formula to find the hypotenuse of a right triangle with 2 sides given?
c2=a2 + b2 where c2 is the hypotenuse squared and "a" and "b" are each side of the triangle Remember the hypotenuse is the length of the triangle opposite the right angle. Rearrange the formula so the hypothenuse c = the square root of a2 + b2
When you use the distance formula what are you building whose hypotenuse connects two given points?
right triangle
Given the legs a and b of a triangle are 3 and 4 then the hypotenuse is?
Given the legs a and b of a triangle are 3 and 4, the hypotenuse is: 5
How do you find area of a 90 degree triangle with hypotenuse only?
The hypotenuse only is not sufficient to determine the area of a right triangle, unless the triangle is stated to be isosceles, or there is some other information that allows determination of the length of a side in addition to the hypotenuse. The area of a right triangle with a given hypotenuse only approaches zero as one of the two acute angles approaches zero degrees.
How do you find sides of right triangle given only the hypotenuse and all angles?
One is the hypotenuse times the sine of one acute angle, the other, the hypotenuse times the sine of the other acute angle (or the cosine of the first).
How do you find the hypotenuse of a right triangle when only a side length and angle is given?
Dependent on what side you are given you would use Sin(Θ) = Opposite/Hypotenuse just rearrange the formula to Hypotenuse = Opposite/Sin(Θ). Or if you are given the adjacent side use Cosine(Θ)=Adjacent/Hypotenuse, then: Hypotenuse = Adjacent/Cosine(Θ)
How do you find the third side of a triangle when two sides are known?
Use Pythagoras' theorem or trigonometry depending on what type of triangle it is. ` Only if it is a right triangle you will be able to use Pythagoras' theorem. This formula states that a^2 + b^2 = c^2 Where a and b are your two of the sides and c is the hypotenuse of the triangle. f you know the hypotenuse but not one of the other sides you can manipulate this formula.
