Answer:
The Required area of Δ is .
Step-by-step explanation:
Diagram of given scenario is shown below.
Given that,
, and °
To find : The area of Δ .
So, from the question
Area of triangle when two sides and one angle (between two known sides) are given , where is the given angle.
Substituting the given values in above to find area of Δ we get,
Therefore, The Required area of Δ is .
I'm assuming the deck is the shaded area.
To find the area of the deck, find the area of the large circle and subtract the area of the small circle from it:
A of large circle: R = (4.2/2) + 1.7 = 3.8; area: 3.8^2 * pi is about 45.3.
A of small circle: r = 4.2/2 = 2.1; area: 2.1^2 * pi is about 13.8
Now, subtract:
45.3 - 13.8 = 31.5 meters squared
