Write down the following functions in Python: a) A function to let the user to input and return the size of a right side (X) and the size of the hypothenuse (H) of a right-angled triangle. H X Y b) A function to calculate the size of the unknown side (Y) of a right-angled triangle by using H2 = x2 + y2 c) A function to display the sizes of the right-angled triangle. Then write down a set of proper Python statements in a main to call these functions in a logical sequence to input the known sizes of a right-angled triangle, finding the measure of the unknown side and printing the sizes of the triangle. 1 A B
