to find other side ;

a = √ hypo^2- leg^2
so, a = √19^2-12^2

therefore it is B ) 14.7 !!

The length of the other leg of the right triangle is 14.7 cm

Properties of a right triangle:

  • one of its side is 90 degree
  • The sides and the angles can be found using trigonometric ratios.

The longest side of a right triangle is the hypotenuse.

Using Pythagoras theorem,

  • c² = a² + b²

where

c = hypotenuse

a and b are the two other legs.

Therefore,

b²= 19² - 12²

b² = 361 - 144

b = √217

b = 14.7 cm
