I
B
A
c
D​

Answer 1

Answer:

x is B , y is C, z is A and w is D

Answer 2

Answer:

Since the sum of the square of the interior angles of a quadrilateral is 360°

Also, 115° + 70° + 60° = 245°

Therefore , ️ABC = 360° - 245° = 115°

Now, X = ext️BCD

=180° - 115° = 65°

Y = 180° - 115° = 110°

Z = 180° - 60° = 120°

W = 180° - 115° = 65°

Therefore, X + Y + Z + W = 65° + 110° + 120° +65° = 360 °
