Use Images and html in questions

Hi
Is there a way to add images as well as html to the questions ?
I tried to add an image using HTML in the question as suggested in one of the forum answer but it didn’t work, on the link if you check question which says “In below figure, A is the centre of the circle. If angle BCD is 65U+00B0, Find angle ACB”
I used an html code to place a ‘degree’ symbol in both question as well as answer but it didn’t work.

Can you please help.
Thank you.
