Question

find the missing angle​

Answer 1

Answer:

x=40°, y=65° and z=75°

Step-by-step explanation:

Angle x=40°, according to alternate interior angle.

And,

x+y=105°, Sum of two interior opposite angles equals to the exterior angle.

Substituting the value of x,

40°+y=105°

y=105°-40°

y=65°

Again,

40°+y+z=180°, straight line.

Substituting the value of y,

40°+65°+z=180°

z+105°=180°

z=180°-105°

z=75°
