IF you have three straight sticks of lengths 5cm 12cm 19cm Can you arrange these sticks into a triangle?
I cut out the lengths to have a visual look at the problem and the answer is NO you cannot arrange 5cm, 12cm, and 19cm into a triangle. Even straightening out the lengths of 5cm and 12cm into a 180 degree angle will not measure out to the 19cm. You cannot have a side that is more than the length of the other two sides combined in a triangle.
A stick is 20cm long.A student makes a 5 percent error in measuring the stick.What are the two possible values for the student's measurement?
5 per cent of 20 is 1. So if the student makes a mistake of exactly 5 per cent then his measurements are 20 +/- 1 cm. That is, 19 or 21 cm.
