Write a list of steps that are needed to find the measure of ∠b

Step-by-step explanation:

113+113=226

360-226=134

134/2=67

Check: 67+67+113+113= 360

67+72=139

180-139=41

A: 72

B: 41

C: 67

Whole circle is 360 degrees and a triangle is 180 degree.

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
