Question

please give me answer step by step.​

Answer 1

Answer:

x=40 degree

y=30 degree

z=50 degree

Answer 2

Answer:please do not give me stars if i am wrong...

Step-by-step explanation:

x+ 30 + 50 = 180(angle sum property)

x+80=180

x=180-80

x=100°

for finding z,

x+z+30=180(angle sum property)

we know x=100°

so,100+z+30=180

130+z=180

z=180-130

therefore,z=50°  

for finding y,

z+40+y=180°,

since z=50°

50+40+y=180

90+y=180

y=180-90

y=90°

therefore ,x=100°

                y=90°

                z=50°

hope it helps....
