Question

can anyone please answer me this question ​

Answer 1

Answer:

1st angle 18

18.4, 18.6+18

=72, 108 +18

=180

Answer 2

4x + 6x+y = 180

10x + y = 180

y = 180-10x

then

6x+y = x + 5y ( corresponding angle)

6x+180-10x = x + 5(180-10x)

-4x +180 = x+ 900 -50x

45x+180 = 900

45x = 900-180

45x = 720

x = 720/45

x = 16

so x = 16

y = 180-10x

180-10*16

180-160

20

so x is 16 and y is 20
