Given, A, B, C are 3 angles of a triangle.
Also, A-B=15° - - >(i)
B-C=30° - - >(ii)
(i) + (ii)
A-B+B-C=15 +30
A-C=45° - - >(iii)
Usin Angle Sum Property, we have
A+B+C=180°-->(iv)
(iv) - (iii) - (ii)
A+B+C-A+C-B+C=180°-45°-30°
3C=105°
C=35°
Now,A-C=45°
Thus,A=45+C
=>A=45°+35°
=>A=80°
Also, B-C=30°
=>B=30+C
=>B=30+35
=> B=65°
Therefore, A=80°,B=65°,C=35°
Also, A-B=15° - - >(i)
B-C=30° - - >(ii)
(i) + (ii)
A-B+B-C=15 +30
A-C=45° - - >(iii)
Usin Angle Sum Property, we have
A+B+C=180°-->(iv)
(iv) - (iii) - (ii)
A+B+C-A+C-B+C=180°-45°-30°
3C=105°
C=35°
Now,A-C=45°
Thus,A=45+C
=>A=45°+35°
=>A=80°
Also, B-C=30°
=>B=30+C
=>B=30+35
=> B=65°
Therefore, A=80°,B=65°,C=35°
