Answer:

pqr116: qrs110 240÷3= 60 260-60 total180

Answer 2

60

Step-by-step explanation:

Draw a parallel line PQ//ST, and point though R.

And name it MN.

$< pqr + < qrm = 180 \\ (interior \: angles \: on \: the \: same \: side \\ of \: the \: transversal) \: \\ 110 + < qrm = 180 \\ < qrm = 180 - 110 \\ < qrm = 70 \\ and \\ < tsr + < srn = 180 \\ (interior \: angles \: on \: the \: same \: side \\ of \: the \: transversal) \\ 130 + < srn = 180 \\ < srn = 180 - 130 \\ < srn = 50 \\ < qrm + < qrs < srn \: = 180 \\ (linear \: pair) \\ 70 + < qrs + 50 = 180 \\ < qrs + 120 = 180 \\ < qrs = 180 - 120 \\ < qrs = 60$

Hope it helps you.
