Answer:
Step-by-step explanation:
<u>Question 1</u>
Two isosceles triangles with repeat 72°.
- x = 180° - 2*72°
- x = 180° - 144°
- x = 36°
<u>Question 2</u>
Isosceles triangle with repeat x/2 angle and a x angle.
- 2(x/2) + x = 180°
- 2x = 180°
- x = 90°
Answer:
200.96 feet
Step-by-step explanation:
We have a pool with a radius of 28 feet.
They also tell us that there is a path around the pool and its width is 4 feet.
Thus:
The radius of the outer edge of the pool path would be equal to the radius of the pool plus the width of the path.
= (28 + 4) feet
= 32 feet
To find the length of the fence, we need to find the circumference of the outside of the pool path. The radius is then equal to 32 feet.
The circumference of the outer edge of the pool path would be equal to the perimeter.
p = 2 * pi * r
replacing
p = 2 * 3.14 * 32
p = 200.96 feet
therefore 200.96 feet are needed
Commutative property of multiplication
First, you need to get rid of the parenthesis, so you need to distribute:
12(–1.4m + 0.4) = m + 0.2
-16.8m + 4.8 = m +0.2
Then subtract both sides by m:
-16.8m - m + 4.8 = m +0.2 - m
-17.8m + 4.8 = 0.2
Subtract both sides by 4.8:
-17.8m + 4.8 - 4.8 = 0.2 - 4.8
-17.8m = -4.6
Now, divide both sides by -17.8:
-17.8m/-17.8 = -4.6/-17.8
m ≈ 0.258
(355*7)+2
=-2,487
(92*7)+4
648
2,487-648
1839/7
=262 and 5/7
