Never,because obtuse angle is an angle measuring between 90 and 180
and if an angle measures 180 then it is a straight angle
i think the answer is 4/11 because the 4 people has a 1% chance out of the 11 people
1 inch equals four 4 because 32 divided by 4 is 8 and 40 divided by 4 is 10
If we had AB: BC: CD, we could easily have solved that problem. In order to combine these ratios, we need to have the same number for BC. We can create this number by finding LCM (Least Common Multiple) for 5 and 3, which is 15. Then, we can write ratios of AB:BC = 6:15 and BC:CD=15:20. Now, we can easily combine these ratios. AB:BC:CD = 6:15:20. Then, 6k+15k+20k = 82 and k=2 cm. And BC = 30 cm
