Answer:
4
Step-by-step explanation:
add the five to the 43, then divide 48 by 12
A=138° B=180° C=180° D=138°
This is because angle QRS and QTS would equal 180° Bc they are supplementary. So 180-42=138. And since they are supplementary and vertical angles, angle ST would also be 42° and QT would also be 138° because angle RS is 138°
