The ones where I had to dance. For me, I am not a big fan of dancing and we had to do the la cha cha as our warm ups everyday. It was so weird. I think I rather do 5 push-ups, 10 sit-ups and jumping jacks for a warm up instead. :V
<span>We have to find the value of x if the measures of the angles of a triangle are: 2 x, 3 x and 4 x. We know that the sum of the measures of the angles of a triangle is 180 degrees. A + B + C = 180. Here we have: A = 2 x, B = 3 x and C = 4 x; 2 x + 3 x + 4 x = 180; 9 x = 180; x = 180 : 9. Answer: x = 20 degrees.</span>
