Answer 1

Answer:

$very \: simple$

$first \: it \: is \: given \: that \: y \: and \: 2x + 15 \: are \: co \: interior$

$and \: y = 3x + 75(opp \: angles)$

$now \\ 2x + 15 + y = 180(co \: int.)$

$therefore \\ 2x + 15 + 3x + 35 = 180 \\ = > 5x + 50 = 180 \\ = > 5x = 130 = > x = \frac{130}{5} = 26$

$now \: we \: know \: that \: y = 3x + 35$

$therefore \\ y = 3(26) + 35 = > 113$

$x = 26 \: and \: y = 113$
