I have 2 questions to ask 1 is divide 180 degrees in a ratio of 4,5 and 9
MAXImum [283]

Here's how to do dividing in a certain ratio:

-- You want to divide up the whole thing in the ratio of
     4 parts, 5 parts, and 9 parts.

-- How many parts all together ?  (4 + 5 + 9) = 18 parts all together.

-- The whole thing is 180, and that's 18 total parts.
    So each part is  (180/18) = 10 degrees.

4 parts = (4 x 10) = 40
5 parts = (5 x 10) = 50
9 parts = (9 x 10) = 90.

Check:  (40 + 50 + 90) = 180 .                yay!

==============================

For the second one, I think there are some words missing.
