A diagonal and shorter side of the rectangle are 190 cm and 120 cm respectively. find the smaller angle between the side and the diagonal.


Sagot :

create a rectangle, then the longer side is 190cm, the shorter side is 120cm.
c²=a²+b² ; where c for the diagonal, a for length, b for width.
tanα= 190/120
α= 57°43'27.68"
