answer this question please it is urgent​

Answer 1

Answer:

a=73degree

b=61degree

c=46degree

d=73degree

Step-by-step explanation:

a+61+46=180degree (semicircle)

a=180-107=73

a=d=73(opposite angles)

b=61degree(opposite angles)

c=46degree(opposite angles)

Answer 2

Answer:

The values of the mentioned angles are :

➜ a° = 73°

➜ b° = 61°

➜ c° = 46°

➜ d° = 73°

Step-by-step explanation:

In the figure :

➜ d° + 61° + 46° = 180° [Linear pair]

➜ d° + 107° = 180°

➜ d° = 180° – 107°

➜ d° = 73°

Also,

➜ d° = a° [Vertically opposite angles]

➜ a° = 73°

Now,

➜ c° = 46° [Vertically opp. angles]

Finally :

➜ b° = 61° [Vertically opp. angles]

Therefore, the values of a, b, c and d in the figure are 73°, 61°, 46° and 73°.
