We assume that the dimension 5 has units of feet.
The area of each triangle will be
A = (1/2)bh
where b=2×(5 ft), h=(5 ft)tan(54°)
Then
A = (1/2)(2×5 ft)(5 ft)(tan(54°)
A = 25×tan(54°) ft²
There are 5 such triangles making up this pentagon, so the total area is
total area = 5×25×tan(54°) ft²
≈ 172 ft²
You should Google it because I forgot but others might know
They are on quarenent one
There are 160,934.4cm in a mile.
1ft.= 30.48cm
1 mile= 5280ft.
5280tf.(30.48cm)= 160,934.4cm
The solution of the given inequality is x<-9.
<h3>What is inequality?</h3>
Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The given inequality is |x + 10|| <1. The inequality will be solved as below:-
|x + 10|| <1
Take 10 to the right side of the inequality and solve it further.
|x || <1 - 10
x < -9
Therefore, the solution of the given inequality is x<-9.
