Using the diagram below, find the measure of each indicated angle.

a= 140 b=140 c= 40 d= 140

Step-by-step explanation:

a b and d are congruent to the given angle and d is supplimentary to c so 140 +40 = 180

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.

solving with completing the square

yes
