If two side of a right angle triangle is 25cm and 15cm what is the length of the unknown side
Studentka2010 [4]

Answer:

29.2 cm

Step-by-step explanation:

The two leg lengths are 15 and 25 cm and we are to find the length of the hypotenuse.  The Pythagorean Theorem applies here because this is a right triangle.  

a^2 + b^2 = c^2 becomes 15^2 + 25^2 = 225 + 625 = 850

The hypotenuse length is thus √850 ≈ 29.2 cm
