<u>First we need to find all the interior angles. So we know that the inside of a triangle (all the angles added up) equals 180. So we need to equal all the inside angles to 180. </u>
2x + x + 60 = 180
<u>Now lets start to solve. First let's subtract the 60 from both sides. </u>
2x + x = 120
<u>Now we need to add the x's together. </u>
3x = 120
<u>Now we must divide the 120 by 3 to get x by itself. </u>
x = 40
<u>Now just replace the x with 40 to find each of the sides. I'm guessing the triangles are reflecting each other so </u><em><u><EHG would be equal to 80. </u></em>
<u>ALSO to check if 40 would be correct, add all the angles together in the same triangle and they SHOULD add up to be 180! Which they do! </u>
Since there are 60 seconds in one minute, we can write this as 146,000 inches per minute. Since there are 60 * 60 = 3600 minutes in one day, we can write it as 525,600,000 inches per day. Since there are about 63360 inches in one mile, the answer is about 8295 miles per day.
