Answer:

Step-by-step explanation:

Construct a perpendicular bisector of segment AB.

Perpendicular bisector is a line that divides the line into two equal halves forming 90° at the intersection point.

So, points A and B will be at the same distance from the intersection point.

If the constructed line (perpendicular bisector) is the reflection axis, then point B will be the refection point of A.

The sum of the external angles of every polygon = 360 degrees
So the n-gon must have its interior angle sum = 360 degrees also.

So what polygon has interior angle sum = 360?

In a park,a sidewalk is built around the edge of a circular pond.The sidewalk is 7 feet wide,and the pond measure 15 feet across

Answer:

91.14 feet

Step-by-step explanation:

Given:

In a park,a sidewalk is built around the edge of a circular pond.

The sidewalk is 7 feet wide, and the pond measure 15 feet across.

Question asked:

What amount of railing would be needed to go completely around the outer edge of the sidewalk?

Solution:

From distance from one edge of the pond to the another = 15 feet

That means diameter of the pond = 15 feet

And width of the sidewalk = 7 feet all around

combined diameter = 15 + 7 + 7 = 29 feet

Radius,r = $\frac{Diameter}{2} =\frac{29}{2} ==14.5\ feet$

That means distance between outer edge of the sidewalk to the center of the circular pond = 14.5 feet

Now, we will have to find circumference of outer circular edge of sidewalk:

$Circumference\ of\ circle=2\pi r$

$=2\times\frac{22}{7} \times14.5\\ \\ =\frac{638}{7} \\ \\ =91.14\ feet$

Therefore, 91.14 feet would be needed to go around the outer edge of the sidewalk.

Find the measure of angle Y. Round your answer to the nearest hundredth. (Please type the numerical answer only)

Sati [7]

Answer:

y = 11.54°

Step-by-step explanation:

Reference angle = y°

Opposite side length = 4

Hypotenuse = 20

Apply trigonometric function SOH:

$Sin(y) = \frac{Opp}{Hyp}$

$Sin(y) = \frac{4}{20}$

$Sin(y) = 0.2$

$y = Sin^{-1}(0.2)$

y = 11.536959° ≈ 11.54° (nearest hundredth)
