a^2 +b^2=c^2

This solution applies for right-angled triangles only:

If you have the length of the two other lines, all you would need to use is the Pythagoras' theorem which states that a2 + b2 = c2 where a and b are the two lines creating the right angle and c is the hypotenuse. This is the most accurate way of finding the hypotenuse, or an unknown length given that of the other two lines. However, if you do not have the length of two lines, this equation doesn't work. If you have the length of a line and another angle, there is sin or cos that be used (depending on which line and which angle is it that you know).

= square root ( 252 + 122 ) = 27.731 to 3 decimal places

If it is a right angle triangle then using Pythagoras; theorem its hypotenuse is 30 times the square root of 2 in inches which is about 42.426 inches rounded to 3 decimal places.

If the hypotenuse has been rounded to 2 decimal places then using Pythagoras the length of the other leg is also 10 cm. Area of the triangle: 0.5*10*10 = 50 square cm

The hypotenuse measures 860.233mm (to 3 decimal places).The square of the hypotenuse is equal to the sum of the squares of the other two sides according to Pythagoras' Theorem. We can write this as a2 = b2 + c2 where a is the hypotenuse and b & c are the other two sides.Thus here we can say that:a2 = 7002 + 5002a2 = 490,000 + 250,000a2 = 740,000a = 860.233 (rounded to 3 decimal places).

Use Pythagoras: 32+62 = 45 and the square root of 45 is about 6.708203932 hypotenuse = 6.71 cm correct to two decimal places
