 11. ❌ Write a function that takes the value of the acute angle of a right-angled triangle and the length of the hypotenuse as arguments, and returns the length of the legs, the area of the triangle and the radius of the circumscribed circle. Write a program to demonstrate how this function works.
 12. ❌ Write a function that takes the base of an isosceles trapezoid as arguments and returns the perimeter, area and height of the trapezoid. Write a program to demonstrate how this function works.
 13. ❌ Write a function that takes age (number of years) as an argument and returns the number of months, days, hours and minutes lived.
