SOME ONE KINDLY HELP ..im stuck after my ans of 540. cant go further. the final ans is 72
Its pretty simple

The sum of angles in any shape is
(n-2)*180, where n is the no. of sides
Regarding the pentagon on one side of the line of symmetry, the sum of angles in the pentagon is
(5-2)*180
=540

Since the shape is symmetrical, angle ABC = x, and angle BCD = 2x
2x + x + 2x + 90 + 90 =540
x = 72

Suppose There is Value 44.6 rounded to 1 DP

So it is definitly Greator than 44.54 As It has to turn 44.6
and Less than 44.65, As it will turn 44.7 then!

So we have >_ (greator than or Equal to ) 44.55 As Lower Bound

< 44.65 as Upper Bounds! ! :)
i cannot get it :cry:

i cannot get it :cry:
Easy as hell

What if we have 4000 (Rounded to nearest 100)

So we will set a Range like this

3950<n<4050

3950: Lower bound, because from this value, it starts to get rounded to 4000

4050: Upper Bound, Because, from this, the value get 4100 if we round and so on! :)

Its soooooooooooooooo simple, just set a range :) :D :)

Hope it helpss :)

Ok if it is correct to the nearest 10 then?
3990 ---> lwer bound
4010---> upper bound
Right? :cautious:

Right? :cautious:
3995 -> LB
4005 -> UP

This just entered my mind:
10/2 = 5
4000-5 = 3995 -> LB
4000 + 5 = 4005 -> UP

A piece of wood is 12cm long to the nearest cm
1/2 = 0.5
12 - 0.5 = 11.5 -> LB
12 + 0.5 = 12.5 -> UB
