Answer:

∠A = 120° (180°-60°)

∠W = 60° (b/c ∠W=∠X)

∠Y = 100° (b/c 180°-80°)

∠X = 60° (180°-120°)

∠Z = 120° (180-60°)

Step-by-step explanation:

im unsure about A and W

Answer:

it is a quadrilateral.

a+60°+120°+80° = 360°

a+260° = 360°

a= 360° - 260°

a = 100°

finding y

y = ?

80°+y =180°. (linear pair)

y = 100° - 80°

y=100°

now, find z .

z + 60° = 180°

z= 180°-60°

z= 120°

w = ?

W+a = 180.

w+100°=180.

w=180°-100°

w=180°

find x,

x+120° = 180°

x= 180°- 120°

x=60°

a = 100°. , x = 60°. , y =100°. , z =120°. , w = 180.
