What is the measure of Arc ED in circle H? 98 POINTS!!
svlad2 [7]

Answer:

90°

Step-by-step explanation:

EG is a straight line

EG = EHD + DHG

DHG is a 90 degree angle

180 = EHD +90

Subtract 90 from each side

180-90= EHD +90-90

90 = EHD

The arc has the same measure as the angle since it is from the center

arc ED = 90

In the given graph, line AB is reflected over the:
melamori03 [73]
Hey there!

The word reflected means when something is basically coping everything that you do. So, for example, when I look in a mirror, the mirror would reflect everything that I would do.

So, from looking at the graph above, as we should <em>remember </em>the \left[\begin{array}{ccc}\boxed{x-axis}\end{array}\right] is the axis that is (horizontal) and the y-axis is the axis that is (vertical).

So, from knowing this information of graphs, we now know that \left[\begin{array}{ccc}AB\end{array}\right] are reflecting over the (x-axis) which is the line that is (horizontal).

Your correct answer would be . . . 

\boxed{\boxed{x-axis \ would \ be \ your \ answer}}

Hope this helps you!

A contractor is building the base of a circular fountain. On the blueprint, the base of the fountain has a diameter of 18 centim
Daniel [21]
The answer is 1808.64 ft²

To calculate area of square we need to find radius r. Radius is a half of a diameter:
r = d/2

The blueprint:
d = 18 cm
r = 18/2 = 9 cm

<span>The blueprint has a scale of three centimeters to four feet. Actual radius r1 is:
</span>3 cm : 4 ft = 18 cm : r1
After crossing the products:
r1 = 4 ft * 18 cm : 3 cm
r1 = 24 ft

The area of the circular base of the fountain is:
A = r1² * π
π = 3.14
r1 = 24 ft

A = 24² * 3.14
A = 1808.64 ft²
