Question

15. Find the values of X,Y,Z and give reasons:
​

Answer 1

Answer:

X = 80

Z = 80

Y = 180 - 80 = 100

Answer 2

Answer:

x = 80°

y = 80°

z = 100°

Step-by-step explanation:

z + 80° = 180°-----(Co-interior angles are supplementary)

z = 180 - 80

z = 100°

y = 80°----(Alternate interior angles are equal)

x = y-------(Corresponding angles are equal)

x =80°

Therefore, x = 80°, y = 80° and z = 100°.
