Estimate the diameter of the supergiant star betelgeuse, using its angular diameter of about 0.05 arcsecond and distance of about 600 light years.
express your answer to three significant figures and include the appropriate units.

Diameter of the star,

Step-by-step explanation:

Given that,

Angular diameter of the star, angle,

Distance,

We need to find the diameter of the supergiant star Betelgeuse. The relationship between the diameter of star and angle subtended is given by :

, d = diameter

or

Hence, this is the required solution.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

good job you smart son of a gun you are smarter that einstein. 7
