Answer: a) x= 68, b) 108°, c) 72°, d) 255°.
Step-by-step explanation:
Since we have given that
The interior angles of hexagon:
(2x+17), (3x - 25), (2x+49), (x+40), (4x-17) and (3x - 4).
So, it becomes :
ii. Find the smallest interior angle of the quadrilateral.
iii. Find the largest exterior angle of the quadrilateral.
iv. Find the largest interior angle of the quadrilateral.
Hence, a) x= 68, b) 108°, c) 72°, d) 255°.
