I've been learning angles on lines and in shapes but I've been struggling with how to go about solving this. Usually you're given more angle values or at least a side value as a starting point - Image of shape but here it's only 90 degrees. I know the parallelogram can be split in to two triangles and that the angles opposite are equal, I also know that the angle left of the 90 is a reflex angle, I just don't know where to go from there and how to use any of that info to get to the next step. I know the answer is x= 52 but the reason wasn't given and I don't understand how they got it. Please can somebody explain it? Thank you.
If you read the test paper, it asks you to measure it, i.e use a protractor instead of using geometry! Especially as it is only one mark they aren't after lots of work!
