-9 tells the distance between her hand and the keys
Answer:
15 sides
Step-by-step explanation:
Interior angle = {n - 2}{180/n}
156 = {n - 2}{180/n}
Cross multiply
156n = {n - 2}180
156n = 180n - 360
180n - 156n = 360
24n = 360
n = 369/24
n = 15
Answer:
309in²
Step-by-step explanation:
Area of an octagon is expressed as;
A=2(1+√2)a²
a is the side length of the octagon
Given
a = 8
Substitute into the formula
A = 2(1+√2)(8)²
A = 2(1+√2)(64)
Expand
A = 2(64+64√2)
A = 128+128√2
A = 128+128(1.414)
A = 128+181.01
A = 309in²
Hence the area of the octagon is 309in²
