Answer:
Distance of object = 0.0144 meter
Step-by-step explanation:
Given:
Angular diameter = 30 arcseconds = 30[100 / 3600]
Length of diameter = 10 cm
Find:
Distance of object
Computation:
Distance of object = [(2)(a)][TanФ / 2]
Distance of object = [(2)(10)][Tan(300 / 7200]
Distance of object = [20][Tan 0.04167]
Distance of object = [20][0.00072]]
Distance of object = 0.0144 meter
Because 13 is a prime number, we cannot use the AC method to simplify.
We can instead use the quadratic formula.

11 +/- √121 - 52 / 2
11 +/- √69 / 2
11 +/- 8.3 / 2
(11 + 8.3)/2 = 9.65
(11 - 8.3)/2 = 1.35
<h3>The roots of the polynomial are 9.65 and 1.35.</h3>
