Question

⑦ In figure, . Find the value of a, b, c and d.​

Answer 1

Answer:

a is 120°

b is 60°

c is 60°

d is 120°

Step-by-step explanation:

• a can be found by 180-60 (interlocking angles)

• The angle adjacent to a is 180-120 which is 60°, b forms

a similar angle to the angle adjacent to a.

So it is also 60°

• c is Vertically opposite to b so it is equal to b (60°)

• d forms a linear/supplementary pair with b , so its 180-60

= 120°
