Hint: = the angles in a four sided figure add up tp 360 degrees
I expect you know but the squares at the angles mean 90 degrees
Yeah I did know that.
so you need to add up the values of the 3 known angles and subtract the result from 360.
I got 334
whats that ? the results of the addition?
nvm 97.. I forgot a number
97 is crorect answer
