Upper and lower bounds degrees °

So the question is 'All the angles in the diagram are measured to the nearest degree , work out the upper and lower bound of x
And the degrees that im given are 59,108,81
I have no idea how to do boumds for degrees as i have tried adding/subtracting .5 to 112 is apparently incorrect
Thanks in advace 😃

I haven't covered the UB and LB of angles yet but would presume the same principle applies as in you find the UB and LB of the given angles THEN do the calculation - which would get you 110.5 and 113.5 as your answers (If I've done the calculations it right that is).

the upper is 113.5 and the lower is 110.5

How ???

I don’t know what I’m doing wrong but I keep getting 110.5 for the upper bound?

Yes that’s what keeps happening to me I keep getting 110.5 for the upper bound

Yes I’m trying to learn how to understand and get 110.5 as the lower bound as I keep getting it for the upper bound

Thanks for asking this question you answered one of my mathswatch questions Thanks

To work out the upper bound for x you work out the lower bounds for the degrees subtracted from 360 giving the highest possible value for x. To work out the lower bound of x you subtract by360 by the upper bounds of the degrees giving the lowest value for x.
