I can't factor this
Answer:
2:1?
Step-by-step explanation:
Well, it makes sense if 1 is 2, for example, then 2 would be 4, so an example of this would be 4:2, and 2 is half of 4. Sorry, I'm not really good with ratios, but I think my answer makes sense. Please double check for me, thanks! :)
Answer:
The angle of elevation from Ethan to the space shuttle is approximately 0.405º.
Step-by-step explanation:
Let O and A the locations observation spot and the space shuttle, respectively. BA is the height of the space shuttle from the ground. All length are measured in miles. We include a simplified geometrical representation of the situation.
Since a right triangle is formed, we can find the angle of elevation (), measured in sexagesimal degrees, by the following inverse trigonometrical relationship:
(1)
Where OB is the distance from the observation spot to the point just below the space shuttle.
If we know that and , then angle of elevation from Ethan to the space shuttle is:
The angle of elevation from Ethan to the space shuttle is approximately 0.405º.
