All the angles should add up to 360 So you know 1 is 110 But you also know 1 is 90 because of the square so you know half is equal to 200 So you are working with 160=360-200 So now you look at the number left and say what number can be doubled and still have enough left over to add 10. So I guess 50 times 2 is 100 And 50 plus 10 is 60 So check does this add up to be 160?yes So x is 50 Good luck Brainliest would be appreciated
