Answer:
∠1=160° and ∠2=20°
Step-by-step explanation:
Let ∠1 = x
∠2 = y
as these two angles are supplementary their sum is 180
that x+y=180 ----(A)
Also given that ∠1 is 20 degree less than nine times the size of ∠2.
Hence
x=9y-20
putting value of x in A and solving for y
9y-20+y=180
10y=180+20
10y=200
y=10
Putting this y in A
x+10=180
x=160
It would not pass under the bridge because ig you divide 162 by 12 it would equal 13.5

The Dewey Decimal Classification System is a method used
to calssify books in the library. It was named after Melvil Dewey who developed
it in 1876. The system uses numbers to organize the subjects of each nonfiction
books and are divided into 10 main subject groups called categories. Each category
is presented by a figure starting from 000 to 999. Each number presents a
special topic. Books with the same number are placed in alphabetical order by
the last name of the author. The first digit of a three digit number signifies
the main class. Suppose you have 500, the 5 in signifies natural sciences and
mathematics. The second digit signifies the division and the last digit signifies
the sections.
