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.
The measure for angle z is 137°. Because angle 43° and angle z are equal to 180°. Which leads u to this equation.
Answer:
b) all interior angles are right angles
