# In , if +=125°and+ =113°,Find ,and.

=67°, =41°, =89°

Given,

+= 125° ___________________ (i)

+ = 113° ___________________ (ii)

We know that sum of angles of triangle = 180°

A + B + C = 180° [Sum of angles]

A + 113°= 180° [From equation (ii)]

A = 6

Value of A = 50° put in equation (i),

+ = 125°

67° + = 108°

= 41°

Value of B = 41° put in equation (ii),

+ = 130°

41° + = 130°

= 89°
