The box's CA measures 4.7 cm in length.
Given data;
△ABC has a right angle at C, BC = 9.2 centimeters, and ∠A=63°
To know CA;
Let CA = x
As per the given case,
In a triangle sum of angles = 180°
90° + 63° + C = 180°
C = 27°
Now,
From the △ABC;
tan 63° = 9.2/x
x = 9.2/tan 63°
x = 4.687
x = 4.7
Therefore, the length of CA in the box is 4.7 cm
