Question

the figures given below, AB | CD. Find the unknown angles, giving
B
0
75
70°
130°
C
F
E A​

Answer 1

Answer:

As AB || CD and BC being transversal

z°=70°. (alternate interior angles)

z°+y°=130°. (exterior angle property)

y°=130°-70°

y°=60°

y°+x°+70°=180°. (straight line and angle)

60°+x°+70°=180°

x°+130°=180°

x°=180°-130°

x°=50°

So, x°=50°, y°=60°, z°=70°
