Short Answer: C
Givens
<QTS = <QTR + RTS
<QTS = 3x + 50
<QTR = 4x - 2
<RTS = 26
Substitute and Solve
3x + 50 = 4x - 2 + 26 Collect like terms on the right.
3x + 50 = 4x + 24 Subtract 24 from both sides.
3x + 50 - 24 = 4x
3x + 26 = 4x Subtract 3x from both sides.
26 = x
Find <QTR
<QTR = 4x - 2
<QTR = 4*26 - 2
<QTR = 104 - 2
<QTR = 102
