Answer 1

Step-by-step explanation:

A, B, C Aare interior angle of triangle ABC

Sum of interior angles =180°

A+B+C=180°

Exterior angles are 180°-A, 180°-B, 180°-C

sum of Exterior angles = 180°-A, + 180°-B + 180°-C

= 540°-(A+B+C)

= 540°-180°

= 360°

sum of Exterior angles of a triangle =360°

Answer 2

Answer:

A, B, C, are interior angles of a triangle ABC

Then the sum of interior angles =180degree

A+B+C=180degree

Then the Exterior angles are 180degree -A, 180degree -B, 180degree -c

then the sum of exterior angles are 180degree -A, +180degree -B+180degree-C

=540degree-(A+B+C)

=the sum of A+ B+C=180

so 540degrees -180degrees

=360degrees

then 360degrees is the answer
