Answer:
200 sq units
Step-by-step explanation:
As you might know, 3 angles of a triangle adds up to 180*. Since you already know the angles are 60* there is one more 60*. So by this you know that all the sides are equal.
As the given states, one side is 20. So following the standard way to get the area of a triangle b*h/2; 20*20 = 400 / 2 = 200 sq units
Mars<span> and Earth orbit the </span>sun<span> at different speeds: Earth has an inside track and gets around the sun more quickly. Plus, both have elliptical orbits, rather than perfect circles. So the distance to Mars from Earth is constantly changing. In theory, the closest the planets could come together would be when Mars is at its </span>closest point<span> to the sun (</span>perihelion) and Earth is at itsfarthest point<span> (</span>aphelion<span>). In that situation, the planets would be 33.9 million miles (54.6 million kilometers) from each other. But that has never happened in recorded history. The closest known approach was 34.8 million miles (56 million km) in 2003 ....... :D!

Step-by-step explanation:
it's is 2.8 km if we round to one decimal place
Answer:
<u>1. 40.97 2. 52.93 3. 32.00 4. 26.00 </u>
Step-by-step explanation:
remember that area =1/2 * b * h so to find base, you can make it the subject of formula i.e
b =area *h/2
or in the caseof h you can do
h= area * b/2
