A window manufacturer is plotting 3 window designs on graph paper. Window A has vertices at ( 1 , 1 ) , ( 1 , 11 ) , ( 9 , 11 ) , and ( 9 , 1 ) . Window B has vertices at ( 1 , 1 ) , ( 5 , 8 ) , and ( 9 , 1 ) . Window C has vertices at ( 1 , 1 ) , ( 1 , 5 ) , ( 17 , 5 ) , and ( 17 , 1 ) . Put the windows in order from largest to smallest area.

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°

on the middle line

step-by-step explanation:

1/5=50

answer is 270 degrees: -

to convert radians to degrees you multiply by 180/π

9π/ 6 * 180 / π

=   9 * 180 / 6

= 9 * 30

=   270 degrees   answer
