R = 2x + 9y [ Given ]
When,
★ Substituting the values in the above equation
=> 13 = 2x + 9 × 3
=> 13 = 2x + 27
=> 13 - 27 = 2x
=> -14 = 2x
=> x = -14/2
=> x = -7
Answer:
x = 67
Step-by-step explanation:
∠ CRQ = ∠ BQR = 113° ( Alternate angles )
∠ CRQ and ∠ CRS are adjacent angles and supplementary, that is
x + 113 = 180 ( subtract 113 from both sides )
x = 67
Yes, they are.
