Between what two measures should the length of the side DB fall?
Asked by Topperlearning User | 14th Oct, 2014, 09:52: AM
Expert Answer:
In a triangle sum of lengths of either two sides is always greater than the third side and also difference of lengths of either two sides is always lesser than the third side.
Here third side AB will be lesser than 7 + 18 = 25 and also it will be greater than 18 - 7 = 11.
That is, 11 < AB < 25
Given AD = 6
i.e. 11 < AD + DB < 25
i.e. 11 < 5 + DB < 25
Thus, 5 < DB < 19
