Two angles are supplementary is the measure of one angle is 54.3 degrees what is the measure of the other angle? Answer to the first decimal place, ie 79.5.

Respuesta :

It would be 125.7 because if it is supplementary that means it has to equal 180. 180-54.3=125.7.

Answer =125.7

Answer: 125.7 degrees

Step-by-step explanation:

supplementary angles add up to 180 degrees.

angle 1 + angle 2 = 180

54.3+angle 2=180.0

54.3-54.3+angle 2=180.0-54.3

angle 2=180.0-54.3

angle 2=125.7 degrees
