Question

calculate the magnitude of angle x qnd angleACB in the following figure if AD || BC :​

Answer 1

Answer:

angle x = 110

angle ACB = 10

Step-by-step explanation:

70+x = 180 ( Linear pair )

x = 180-70

x = 110°

Now ,

angle ACB + angle x + angle ABC = 180 (Angle sum property of ∆ )

ACB + 110° + 60 ° = 180

ACB + 170° = 180 °

ACB = 180 - 170

ACB = 10°
