I have been practising trig on the bb bitesize maths website. It keeps telling me that I have given the wrong answer to the following problem.(adsbygoogle = window.adsbygoogle || []).push({});

Draw a triangle XYZ with Y being a right angle. The angle at X is 42 degrees and the length of YZ is 3.7cm.

The question requires you to find the length of XY (the adjacent side) to 3 s.f.

I did the calculation tan42 = 3.7/XY and came up with a length of 4.11cm. I also tried 4.10cm (without rounding up), but according to the website both answers are wrong.

Can anyone tell me where I am going wrong?

Thanks
