Step-by-step explanation:
We use trigonometry to find the angle of elevation.
From the diagram, the angle of elevation of the sun is
Recall the mnemonics SOH CAH TOA.
Therefore the angle of elevation of the sun is

Equation of the circle is (x - 6)² +(y-7)² = 4.
<h3>What is a Circle ?</h3>A figure having round shape and all the points lie on the same plane is called a circle.
Equation of a circle can be formed using centre of the circle and radius of the circle.
(x-h)² +(y-k)² = r²
where (h,k) is the vertex and 'r' is the radius.
From the given graph the centre of the circle is at (6,7)
and radius of the circle is 2 units
(h,k) is (6,7)
and r= 2
Substituting all the values
The equation of the circle
(x - 6)² +(y-7)² = 2² = 4
Equation of the circle is (x - 6)² +(y-7)² = 4
