Answer:
The answer is "measure the parallax and use it in calculations".
Explanation:
In this question, the above choice is correct because, in the summer and winter, light is observed from both parts of a planet. An astronomer can once, again and 6 weeks later calculate the position of a star and then compute the perceived shift of location. It measures which utilizes parallax and its best method for calculating the approximate distance between the star, as well as the planet.
Their alignment. Are they straight? Crooked? Missing teeth ?
Patent law in the US is the Patent Act. It protects new inventions and establishes the US Patent Office to accept patent applications. Its authority is from the US Constitution which says "Congress shall have power to promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries."
Answer:
Let AB be the igloo
C be the polar bear
According to the given information:
· ∠ABC = 90° (The igloo and the ground)
· ∠ACB = 17° (The foot of the polar bear to the top of the igloo)
· BC would be the distance between the polar bear and the igloo, BC = 131 ft
The height of the igloo is:
tan 17° = AB / BC
AB = tan 17° × BC
AB = tan 17° × 131
AB = 40.05 ft
