$(9x + 17) +2 \times ( 5x + 15 ) + (6x - 12) = 360 \\$

$9x + 17 + 10x + 30 + 6x - 12 = 360 \\$

$9x + 10x + 6x + 17 + 30 - 12 = 360 \\$

Collect like terms

$25x + 35 = 360$

Subtract sides 35

$25x + 35 - 35 = 360 - 35$

$25x = 325$

Divide sides by 25

$\frac{25x}{25} = \frac{325}{25} \\$

$x = 13$

Thus ;

$RQ \: \: arc =2 \times (5x + 15)$

$RQ \: \: arc = 10x + 30$

$RQ \: \: arc = 10(13) + 30$

$RQ \: \: arc = 130 + 30$

$RQ \: \: arc = 160°$
