4- A building 19 m tall casts a shadow of 19 m along the level ground.

1.	4- A building 19 m tall casts a shadow of 19 m along the level ground. At what angle do therays of the sun hit the ground?
Answer» yes a building has 19 m tall Use this theoremIf opposite angles are equal then opposite sides are equalHere the two sides are equal then angles are equal.A right angled triangle is formed if we draw the picture.One of the angles is 90The sum of the remaining angles = 180-90=90Sum of the angles in a triangle is equal to 180Since the angles are equal the value of the angles are 90/2=45The Sun rays hit the ground at 45. Use this theoremIf opposite angles are equal then opposite sides are equalHere the two sides are equal then angles are equal.A right angled triangle is formed if we draw the picture.One of the angles is 90The sum of the remaining angles = 180-90=90Sum of the angles in a triangle is equal to 180Since the angles are equal the value of the angles are 90/2=45The Sun rays hit the ground at 45. teta equal 45'because by the right angle triangle tan45
