Given :
A T.V. is measure by its diagonal.
To Find :
If the height of a 60 inch T.V. is 32 inches, what is the width.
Solution :
We know, T.V. is rectangular in shape and angle between two sides of rectangular is 90° .
Let, width of T.V. is x.
Applying Pythagoras theorem in sides, we get :

Therefore, width of T.V. is 55.42 inches.
Angle 1 would 107° since a and b are parallel. Angle 2 would be 180° - 107° = 73°.
