Question

ACTIVITY 1.
In each of the given figure, find the measure of the unknown angle (x).
​

Answer 1

Step-by-step explanation:

a = d (vertically opposite angles)

d = f (corresponding angles)

f = 110° (vertically opposite angles)

∴ a = d = f = 110°

e + 110° = 180° (co-interior angles)

∴ e = 180°- 110° = 70°

b = c (vertically opposite angles)

b = e (corresponding angles)

e = g (vertically opposite angles)

∴ b = c = e = g = 70° ”

Hence a = 110°, b = 70°, e = 70°, d = 110°, e = 70°,f=110° and g = 70°
