The sun's angular diameter is measured to be 1920''. The distance D of the sun from the earth is 1.496 *10power -11m. What is the diameter of the sun ? will you pzzz explain me the answer .
Given D = 1.496×1011 m
Θ = 1920“=(1920/60×60) o = 0.53o
As angle Θ is very small the triangle is approximately a right triangle
