[2 marks] This is a 4 -sided shape, to work out the interior angles we calculate the following: (\textcolor {red} {n}-2)\times 180 =360\degree. Next we can work out the size of \angle CDB as angles on a straight line add up to 180\degree. 180 - 121 = 59\degree. Now we know the other 3 interior angles, we get that.
