Answer:
see explanation
Step-by-step explanation:
∠c = ∠ a = 47° ( vertical angles )
∠c and ∠b form a straight angle and are supplementary, thus
∠c + ∠b = 180, that is
47 + ∠b = 180 ( subtract 47 from both sides )
∠b = 133°
∠d = ∠b = 133° ( vertical angles )
That is a = c = 47° and b = d = 133°
The sum of the 4 angles = 133° + 47° + 47° + 133° = 360°
360° is the sum of the angles round a point , hence answer is correct
Answer:
300
Step-by-step explanation:
it is rounded to 300 because the number 342 is closer to 300 than it is to 400 if its 350 and up then it would be rounded to 400 but its not so its rounded to 300
