Answer 1

Step-by-step explanation:

4 a)

$50 + y = 180 \\ y = 180 - 5 0\\ y = 130 \\ \\ y = z |{cointerior \: angles} | \\ z = 130 \\ \\ z + angledown \: to \: y \: = 180 \\ \\ let \: angle \: down \: to \: y \: be \: a \\ \\ z + a = 180 \\ 130 + a = 180 \\ a = 180 - 130 = 50 \\ x + y + a + 50 = 360 \\ x + 130 + 50 + 50 = 360 \\ x = 360 - 230 \\ x =130$
