Question

find x+y+z+w from figure​

Answer 1

Step-by-step explanation:

PROCEDURE -

Since, the sum of the measures of interior angles of a quadrilateral is 360°

Also, 115° + 70°+ 60°= 245°

∴∠ABC = 360° − 245° = 115°

Now, x = ext∠BCD = 180° − 115° = 65°

=> y = 180° − 70° = 110°

=> z = 180° − 60° = 120°

=> w = 180° − 115° = 65°

∴ x + y + z + w = 65° + 110° + 120° + 65° =360°
