b = 9
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 12² = 15²
b² + 144 = 225 ( subtract 144 from both sides )
b² = 81 ( take the square root of both sides )
b = = 9
Answer:
Recursive algorithms call itself with simpler or smaller input values. They can be used to solve large problems by using the solutions to minor parts of the problem, these minor problems are then further broken down to solvable cases.
