we will use formula
where
theta is angle
n is number of sides
we are given
n=15
we can plug it
now, we can solve for theta
so,
option-D.........Answer
Answer:
Step-by-step explanation:
The sum of adjacent angles traversed by a line must equal 180 degrees.
128+x=180
x=52
52 = 50
512= 500
500/50 = 10

There are 12 more of white and blue cars than silver and red cars
Step-by-step explanation:
Step 1 :
Number of black cars counted by Ed = 23
Number of red cars counted by Ed = 9
Number of blue cars counted by Ed = 17
Number of white cars counted by Ed = 25
Number of silver cars counted by Ed = 21
We need to determine how many more white and blue cars are there than silver and red cars
Step 2 :
Total of white and blue cars = 25 + 17 = 42 cars
Total of sliver and red cars = 21 + 9 = 30 cars
Difference = 42 - 30 = 12 cars
Hence there are 12 more of white and blue cars than silver and red cars
Step 3 :
Answer :
There are 12 more of blue and white cars than red and silver cars
