Step-by-step explanation:

$(1) \: \: \: 4x + 5x = 360$

$9x = 360$

$x = 40$

$4x = 4(40) = 80 \: degree$

$5x = 5(40) = 200degree$

$(2) \: \: \: \: 2x - 5 + 3(x - 10) = 360$

$2x - 5 + 3x - 30 = 360$

$5x - 35 = 360$

$5x = 360 + 35 = 395$

$5x = 395$

$x = \frac{395}{5} = 79$

$2x - 5 = 2(79) - 5 = 158 - 5 = 153 \: degree$

$3x - 30 = 3(79) - 30 = 237 - 30 = 207degree$
