Answer:
6
Step-by-step explanation:
The order of the polynomial is 6 (look at the highest exponent). So there are 6 roots.
It's 280706 keeping all the place values together in the order
Since s and t are complimentary, that means ∠s + ∠t = 90
From the picture, we also know that ∠t + ∠LGM = 90
Set them equal to each other:
∠s + ∠t = ∠t + ∠LGM, solve:
∠s = ∠LGM
Now using the fact that tangent = opposite/adjacent:
tan (∠s) = 
tan (∠s) = 
Set them equal to each other to get:
= 
Solve:

Part B:
Using tan (∠s) = 
We get:
meters
Hope that helps!
First you subtract 15 from 26 and get 11.
Second you multiply 11 by 2 and get 22.
Therefore your answer is 22.
