Question

answer to the question​

Answer 1

Answer:

z = (x+y) - 180

Step-by-step explanation:

Let the triangle be ∆ABC.

So , B = 180°-y°(Straight Angle)

C = 180°-x°(Straight Angle)

A = z°( Vertically Opposite Angle)

We know , A+B+C=180

=> (z) + (180-y) + (180-x) = 180

=> 360 + z -(x+y) = 180

=> z - (x+y) = 180-360 = -180

=> z = (x+y) - 180 [ Answer ]

Answer 2

Answer:

180-x-y
