8 % = .08 = 8/100 = 2/25
The slope is 2/25
Each Interior Angle = 180° - (360 / sides)
144 = 180 - (360 / sides)
(360 / sides) = 36
sides = 360 / 36
sides = 10
It is a decagon.

Answer:
Step-by-step explanation:
If the triangle is equilateral, it means that all the sides are the same. Since there are 3 sides in a triangle, each side is 24/3 = 8
Now, in order to find the height, we can use the pythagoeren theroem. Notice that the height bisects(splits the side) into two equal parts, which each part having the length 8/2 = 4
So we have
Answer:
- <u>Surface Area = 188.4 square yards</u>
- <u>Volume = 216 cubic yards</u>
Step-by-step explanation:
Finding the hypotenuse of the triangular side :
- Applying Pythagorean theorem
- √6² + 6²
- √2 x 6²
- 6√2
Finding Surface Area :
- Area (2 triangles) + Area (2 smaller rectangles) + Area (larger rectangle)
- 2 x 1/2 x 6 x 6 + 2 x 12 x 6 + 12 x 6√2
- 36 + 144 + 6√2
- 180 + 6√2
- 6 (30 + √2)
- 6 (30 + 1.4)
- 6 (31.4)
- <u>188.4 square yards</u>
<u></u>
Finding Volume :
- 1/2LWH
- 1/2 x 12 x 6 x 6
- 6³
- <u>216 cubic yards</u>
Hello :
<span>the nth term is : an= a1×q^(n-1)....... a1 = 8 and q = -3
</span>an= 8×(-3)^(n-1)<span>
