Answer:2. It’s 24.58
How many boards did the volunteers supply round your calculations to the nearest hundred- 13.44
How many whole boards-14
Step-by-step explanation:
The area of the parallelogram is 40 centimeters
a.
Scottie = 30
Top of the lighthouse = 45 (30+15)
The boat = 0
The fish = -10
b.
10 + 30 = 40
You have to find the GCF of 140 and 180.
The GCF is 20 so thats your answer.
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!
