It's even better if you have a telescope or binoculars. Both allow you to see planets, the moon, and stars even closer. Telescopes are more powerful than binoculars. With a telescope, you can see the moon close enough to see its features. Labeled images like this one can help you find different places on the moon or other objects in the night sky. Even without a telescope, you will still be able to find some of these place
What does this mean for you and your stargazing? Well, you may not make any major discoveries like Galileo did, but you can look up at the sky in your own backyard. You can see the moon and many of the same stars that early astronomers saw. You can even see planets. For example, this is an image of Venus, Mars, and the moon, as seen from Earth without a telescope or binoculars. It is amazing what you can find if you just look up!
What evidence does the author use to support the idea that a telescope is not needed to learn about Earth's moon?
A. Early astronomers saw many of the same starts without a telescope.
B. Looking up at the sky is enjoyable even if you don't have special tools.
C. You can see even more detail in the sky if you use a telescope.
D. You can see some of the features of the moon without a telescope.

The amount of fencing Madisyn needs is approximately 20.77 m
Step-by-step explanation:
The coordinates of the vertices of the triangular garden are;
A(0, 6), B(6, 5), and C(5, -1)
The length of the sides of the triangle can be found through the given coordinates and the distance between coordinates formula presented as follows;
Therefore, the length of AB is![\sqrt{\left (5-6 \right )^{2}+\left (6-0 \right )^{2}} = \sqrt{37}](/tpl/images/0851/6815/940ec.png)
The length of BC is![\sqrt{\left (5-(-1) \right )^{2}+\left (6-5 \right )^{2}} = \sqrt{37}](/tpl/images/0851/6815/83d15.png)
The length of AC is![\sqrt{\left (6-(-1) \right )^{2}+\left (0-5 \right )^{2}} = \sqrt{74}](/tpl/images/0851/6815/a8add.png)
Therefore;
The amount of fencing Madisyn needs = The length of the sides of the triangular garden
The length of the sides of the triangular garden = The length of AB + The length of BC + The length of AC
The length of the sides of the triangular garden = √37 + √37 + √74 ≈ 20.77 m.
The amount of fencing Madisyn needs ≈ 20.77 m.
