<h2>60,47,73</h2>
Step-by-step explanation:
Let the first angle be
degrees
Let the second angle be
degrees
Let the third angle be
degrees
It is given that sum of angles is
degrees.
so,
...(i)
It is given that sum of the measures of the second and third angles is two times the measure of the first angle.
...(ii)
It is given that the third angle is 26 more than the second.
...(iii)
using (ii) and (iii),


using (i),(ii) and (iii),
