The measure of the middle angle of a triangle is twice the smallest angle. The sum of the middle angle and the largest angle is 5 times the smallest angle. Find the measures of the angles.

m = 2s

m + l = 5s    or

   2s + l = 5s    which shows   l = 3s  

 

summed , the angles = 180

 

s    + 2s   + 3s   = 180

   s = 30      then    l = 90      m = 60   degrees
