Respuesta :

The sum of the angles of a triangle is equal to 180°.

p+80°+20° = 180°

p = 180° - 80° - 20°

p = 80°

_________________________

q + 45° + 55° = 180°

q = 180° - 45° - 55°

q = 80°

______________________________

p = q = 80°

B)
The answer is B. 180 degrees minus 80 degrees minus 20 degrees equal 80 degrees. 180 minus 55 degrees minus 45 degrees equal 80 degrees.
