Question 833162
Since the total of the 3 angles = 180,
the remaining two angles = 180 - 82 = 98

Given a ratio of 2:5
The smaller angle will be {{{(2/(2+5))*98}}}
{{{(2/(7))*98}}} = 28
Since the two angles total 98 the other angle is 70 degrees.
The two angles are 28 and 70 degrees.
Notice 28/70 = 2/5 or 2:5
