Work out the size of angle x.
33°
20°
165°

X = 52°

Step-by-step explanation:

it all has to add up to 360°

33 + 20 + 165 = 218

The other missing angle is an acute angle witch means its 90°

218 + 90 = 308

360 - 308 = 52°

x = 52°

i dont get it. where are the "descriptions"?

828. all there is to it!

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!
