Answer:

The half of the moon facing the sun is always lit, but the different phases we view from Earth happen because:

<h2>we only see parts of the lit side as the moon goes around the Earth.</h2>

Step-by-step explanation:

The moon phases occur because the Sun lights different parts of the Moon as the Moon revolves around the Earth. So, we only see the parts of the Moon that are being lit while it orbits Earth.

PLEASE HELP

Look at the picture.

Use the Pythagorean Teorem:
$l^2+(5l)^2=d^2\\l^2+5^2l^2=d^2\\d^2=l^2+25l^2\\d^2=26l^2\\d=\sqrt{26}^2\\d=\sqrt{26}\cdot\sqrt{l^2}\\\boxed{d=l\sqrt{26}}$

Answer:

x = -7

Step-by-step explanation:

(x + 14) + (x + 12) = 12

Combine like terms

2x + 26 = 12

Subtract 26 from both sides

2x = -14

Divide both sides by 2

x = -7

Diana works in a building that is 130 feet tall. She is outside, looking up at the building at an angle of 37° from her feet to

Olegator [25]

Answer:

Let x be her initial distance from the building, then tan 37 = 130/x

x = 130/tan 37 = 130/0.7536 = 172.5 feet

Let y be her distance from the building after moving forward, then

tan 40 = 130/y

y = 130/tan 40 = 130/0.8391 = 154.9

After moving forward, she is 172.5 - 154.9 = 17.6 ft closer.
