The height of the tree, h = 14 ft
The height of the shadow, b = 16 ft
We need to find the angle of elevation of the sun from the ground. Let the angle be θ. We can use trigonometry to find it. So,
So, the required angle of elevation of the sun is equal to .
The internal angle sum of a quadrilateral is :
C. 360°
The sum of internal angles of a polygon is determined by a formula :
where n represents number of sides.
In a quadrilateral there are four sides,
So, plugging 4 in the formula :
