Answer 1

Answer:

angle 160 degree =angle y (voa)

angle y = 160 degree

the measurements of all angles are =360

angle x=z (voa) ~angle x and z common =x

by angle sum property in this fig

160+y+x+z=360

160+160+x+x=360

320+2x=360

2x=40

x=20

angle y is 160 and x and z is 20 degree

please follow me

Answer 2

Answer:

20, 160 and 20

Step-by-step explanation:

x = z and y = 160°.

x + y + z + 160 = 360{Straight lines}   --- (1)

x + 160 + z + 160 = 360  

x + 160 + x + 160 = 360

2x + 320 = 360

2x = 40

x = 20

Then,

z = 20

Place x and z values in (1).

20 + y + 20 + 160 = 360

=> y = 160

Hence, the angles are 20, 160, 20.
