Answer:
The area of the pentagon is approximately 21 square units
Step-by-step explanation:
The radius of the circle in which the regular pentagon is inscribed, r = 3
The area of a pentagon, 'A', inscribed in a circle with radius, r is given as follows;
A = 5×(1/2) ×2×r·sin(32°)×r·cos(32°) = (5/2)×r²×sin(72°)
Therefore, the area of the pentagon, A = (5/2)×3²×sin(72°) ≈ 21.3987716166 ≈ 21
The area of the pentagon, A ≈ 21 square units.
Answer:
B 1.8
Step-by-step explanation:
Answer:
30
Step-by-step explanation:
let EFH = x
Let GFH = y
x + y = 90
x = 2y
Substitute: 2y + y = 90
3y = 90
y = 30
a. The equation computed shows that the number of paid vacation days has she earned will be 17 days.
b. The time when she will reach the maximum number of paid vacation days allowed is 6 years.
<h3>How to compute the equation?</h3>
a. The equation computed shows that the number of paid vacation days has she earned will be:
= 2 + 3x
x = 5
= 2 + 3(5)
= 2 + 15
= 17 days.
b. The maximum number of days for a pod vacation will be:
= 4 × 5
= 20 days.
The time when she will reach the maximum number of paid vacation days allowed will be:
20 = 3x + 2
3x = 20 - 2.
3x = 18
x = 18/3
x = 6 years
