What is the measure of Angle "c" of a triangle if Angle "a" is 57 degrees and Angle "b" is 114 degrees.

Angle "c" would be 9 degrees (a very small angle!)

Step-by-step explanation:

In a triangle, all of the angles must equal 180 degrees.

57, the measure of angle "a", plus 114, the measure of angle "b", would equal 171 degrees.

So, 180 - 171 = 9, which would be the value of the remaining angle "c"

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
