So the problem is number 8 and number 9 8.If mABC is one degree less than three times mABD and mDBC = 47°,find each measure.
9.If QS bisects PQT, mSQT = (8x – 25)°, mPQT = (9x + 34)°, and mSQR = 112°
, find each measure.

Ineed if you could explain and give me the answer you! this needs done
