Three angles of a quadrilateral are equal and the measure of the fourth angle is 120. Find the measure of each of the equal angles.

Answer 1

Answer:Its easy, the simplest method is described below....

Add the ratios...1+2+3+4=10

Now find the angles as follows,

1st angle = (1/10)*360=36°

2nd angle =(2/10)*360=72°

3rd angle =(3/10)*360°=108°

4th angle =(4/10)*360°=144°

These are following angles.
