Given the figure below, we are to find the area of the regular polygon with are also to bear in mind that what is shown is the apothem.
let's get the area of a regular polygon with an apothem first.
Area = 1/2nsa
Where:
n is the number of sides
s is the side length
a is the apothem
recall that:
n = 5
s =7.5
a = 5.1
input into the formula.
Area = 1/2(5)(7.5)(5.1)
Area = 1/2(191.25)
Area = 95.625
Therefore, the area of the regular polygon is 95.6

Answer: E = 56
Step-by-step explanation:
E is proportional to √C
To remove proportionality, introduce a constant (k).
E = k × √C
From question,
E = 40 and C = 25
So,
40 = k ×√25
40 = k × 5
k = 8
Now,
C = 49
k = 8
E = ?
E = k√C
E = 8 × √49
E = 8 × 7
E = 56
Answer:
<h2>
The right option is twelve-fifths</h2>
Step-by-step explanation:
Given a right angle triangle ABC as shown in the diagram. If ∠BCA = 90°, the hypotenuse AB = 26, AC = 10 and BC = 24.
Using the SOH, CAH, TOA trigonometry identity, SInce we are to find tanA, we will use TOA. According to TOA;
Tan (A) = opp/adj
Taken BC as opposite side since it is facing angle A directly and AC as the adjacent;
tan(A) = BC/AC
tan(A) = 24/10
tan(A) = 12/5
The right option is therefore twelve-fifths
