Answer:
a = 60 degrees and b = 30 degrees
Step-by-step explanation:
30 degrees (line E) = angle b
angle b = 30 degrees
there is a right angle plus the 30 degrees = 120 degrees.
180 - 120 = 60 degrees which is angle a
362/1000 = 181/500
I only know that one, sorry
Tony’s backpack can carry weight up to 22 but not more that that
If the variable n represents the total weight carried by tony
Then ; n less than or equal to (n=1+3+3b
=4+3b
Where b represents book
4+3b is less or equal to 22
3b is less or equal to 18
b is less or equal to 6
Therefore Tony’s backpack cannot carry more than 6 books
I really don’t know sorry I’m doing it for the points
