the angles are 80 degree and 100 degree. Method- 4:5=4x and 5x , 4x+5x=180 , 9x=180, x=180/9, x=20, therefore, 4:5= 4*20and 5*20 4:5=80 and 100

Very good Nilarka Pahari and Khushie. Friends , the correct answer is B only. Just try to see . Tilt your head to your right and try to see the cuts at the end of the ribbons . You will find the error of your own. Did you find that? I know that only 5 to 37 percent of you can nfind the eight angles. Be very accurate and intelligent. I also did the same mistake while giving the test . Please look carefully!
