Question

Hello everyone! if anyone knows how to do trigonometry please answer my question (with as much detail as you can) as im a little bit stuck thank youuu in advance :)

Find the size of all angles of a right angled triangles with sides 12cm, 13cm and 5cm

Answer 1

AB = 5cm

AC = 12cm

BC = 13cm

A = 90 deg

B= arctan(AC/AB)=arctan(12/5) =67.38 deg

C=arctan(AB/AC) =arctan(5/12) = 22.62 deg
