Here, the figure is parallelogram, where sum of complimentary angles are equal to 180 degree. So, 5x + 35 + 5x + 45 = 180 10x + 80 = 180 10x = 180 - 80 x = 100 / 10 x = 10
oooh i love these problems i would be more then happy to help you! the key is to set them equal like this... 5x+45=5x+35.... then you use PEMDAS....... subtract 35 from 45 and u get 10........ then subtract the X's and you get X=10 Hope this helps
