Two angles are not enough to define the length of anything in a triangle.

You also need to know the length of one side.

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.


Where can you find the hypotenuse of a right triangle?

the hypotenuse is the side of the right triangle that is opposite of the 90 degree angle. To figure out the length of the hypotenuse you can use a2 + b2 = c2 (if you know the length of the other two sides) If you don't that you can probably use the sine or the cosine equation. (as long as you know at least one of the angles)


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 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.


What is length of the equal sides of an isosceles triangle where the two equal angles are 20 degrees and the third side is 12?

Treat it as being two right angled triangles by halving the base and use the cosine ratio to find its hypotenuse (which will be one of the equal sides) cosine = adjacent/hypotenuse hypotenuse = adjacent/cosine hypotenuse = 6/cosine 20 degrees = 6.385066635 The length of the equal sides = 6.4 units correct to one decimal place.

How do you find the length of the two legs of a triangle when you only have the hypotenuse?

You can't. You need at least another side length or two corner angles.

If one leg of the isosceles right triangle is 2 feet long find the length of the hypotenuse?

Isosceles triangles have two sides which are the same length and two angles which are equal. So if your right triangle has one side of length 2 feet, which is not the hypotenuse, then the remaining side must also be 2 feet long. We know that the square of the length of the hypotenuse is equal to the squares of the other two sides. 2 squared is 4. So the squares of the two sides are 4 + 4 which equals 8. Now we just find the square root of 8, which is 2.8284... So the length of the hypotenuse is 2.83 Feet (to two decimal places). Or, In a right isosceles triangle, the two base angles equal 45°. Since the length leg is 2 ft, then the hypotenuse length would be equal to 2√2 or approximately to 2.83 ft. sin 45° = leg/hypotenuse hypotenuse = 2/sin 45° hypotenuse = 2/(√2/2) hypotenuse = 4/√2 hypotenuse = 4√2/2 hypotenuse = 2√2 °


How do you find the angle of a right triangle with the length of two legs?

-- Like every triangle, a right triangle has three interior angles.-- Unlike any other triangle, one of the angles in a right triangle is a right angle.The other two are both acute angles.-- One acute angle is the angle whose cosine is length of one leg / length of hypotenuse-- Other acute angle is the angle whose sine is length of the same leg / length of the hypotenuse-- The length of the hypotenuse is the square root of [ (length of one leg)2 + length of other leg)2 ]


Find hypotenuse only using opposite and angle?

In a right angles triangle the sides are named the hypotenuse (the side opposite the right angle) and the other two sides are called the adjacent and the opposite sides. 1) The sine of an angle = length of the opposite side ÷ length of the hypotenuse. 2) The cosine of an angle = length of the adjacent side ÷ length of the hypotenuse. Using 1) The length of the hypotenuse = length of the opposite side ÷ the sine of the angle. Using tables or a calculator obtain the sine of the angle and divide this into the length of the opposite side. The result will be the length of the hypotenuse.

What is the length of a hypotenuse?

A hypotenuse is the longest side of a right angled triangle. The length of a hypotenuse can be found using the Pythagorean Theorem. This states that in a right angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. This means that to find the length of the hypotenuse, you need to know the lengths of the other two sides.


How do you use the Pythagorean theorem to find the length of the hypotenuse if you know the lengths of the other two sides?

Square the two sides then add them up and the square root of this sum gives the length of the hypotenuse
