Use Pythagoras' theorem: the square on the hypotenuse is equal in area to the sum of the squares on the two other sides.
So if the unknown side is the hypotenuse:
62 + 82 = x2
x2 = 100
x = 10 (This is fundamentally the same as the classic 3-4-5 triangle, employed by the ancient Egyptians to form right angles.) If the 8 foot side is the hypotenuse: 62 + x2 = 82
x2 = 64 - 36 = 28
x = 5.29 (to two decimal places).
90 degrees is the measure of a right angle
A right angle measures 90o (degrees).
Yes a right angle is defined as an angle that measures exactly 900
It is a right angle triangle and the 3rd angle will measure 30 degrees
The corner of a square measures 90 degrees which is a right angle.
