Question

what is angle x , angle y , angle z and sum of three angles,x + y + z =?​

Answer 1

Answer:

x+y =90

Z+72=180

z=108

then x+y+z=198

Answer 2

Answer:

198°

Step-by-step explanation:

The sum of all angles around a point is 360°

so,

∠COD + ∠DOB + ∠BOE + ∠EOA +∠AOC =360°

90°  + y° + 72° + z° + x° = 360°

162 + x + y + z = 360

x + y + z = 360-162

x+y+z=198
