Question

5.4 In Fig. 32, lines m and p are parallel. Find the unknown angles and give reasons for your answers. ​

Answer 1

Answer:

the value of x will be 120° and y = 40° and z = 80°

Step-by-step explanation:

since the lines m and p are parallel so angle x will be 120° because they are adjacent angle and y also will be adjacent to angle C so it will be 40°.

Now x = y+z because it's a property of triangle called the exterior angle sum property, in which an exterior angle of a triangle is equal to its two opposite non adjacent interior angle. so z will be x-y which is 120° - 40°= 80°
