Answer:
16
Step-by-step explanation:
perimeter of B = 21
divide by 3 to get each side: 21/3 = 7 = Y
perimeter of hexagon is 50. subtract 2Y: 50 - 14 = 36
divide 36 by 4 to find X = 9
add X + Y
X is 90 degrees. If AB is the diameter, then it passes through the centre. X is 90 degrees because the angle in a semicircle is always a right angle.
