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°
Answer:
x=100
not sure about the answer
10 because there is a 2.5 difference between each y value. Therefore , an X value of 4 would be 10
