Question

what is the answer of the question​

Answer 1

Step-by-step explanation:

Co interior angles is =180

Answer 2

Answer:

y + z = 180°. ...........(i)

x + y = 180°. ...........(ii)

now,

y : z = 3 : 7

Let y = 3k & z = 7k

from (i)

3k + 7k = 180 i.e 10k = 180 so k = 18

y = 3 × 18 = 54

from (ii)

x = 180 – y = 180–54 = 126°.

Ans.
