Check it carefully next time.!!
The answer is 112 centimeters.
As this problem represents a right triangle, here we need to apply the Pythagorean Theorem.
- h = √113² - 15²
- h = √12769 - 225
- h = √12544
- h = 112 centimeters
Use o fato de que o determinante de qualquer matriz quadrada é o mesmo da sua transposta.
