Michael and Derrick each completed a separate proof to show that corresponding angles AKG and ELK are congruent. Who completed the proof incorrectly? Explain.

see below

Step-by-step explanation:

Michael is incorrect

AKG and AKL are not vertical angles

Michael

Step-by-step explanation:

Angles AKG and BKL are vertically opposite angles.

Angles AKG and AKL are supplementary angles, not vertically opposite angles.

Therefore, Derrick's proof is correct. Michael's is incorrect

  b)  2 7/12 ft

Step-by-step explanation:

The difference is ...

  (17 5/12 ft) - (14 5/6 ft) = (17 -14) ft + (5/12 -5/6) ft

  = 3 ft + (5/12 -10/12) ft = 3 ft - 5/12 ft

  = 2 7/12 ft
