hey guys please help me out! tomorrow is my exam so please find out the answer fast as possible.plzz.​

Answer 1

Answer:

150/underoot13

Step-by-step explanation:

If theta is the angle between diagonal and the side of the rectangle then

AB/BC = cotø

if cotø = 3/2 then sinø = 2/underoot 13

and sin ø = BC/AC

    2/underoot 13 = BC / 15

so BC = 30/ underoot 13

similarly cos ø = 3/underoot 13

            and cos ø = AB/AC =AB/15

                   3/underoot 15 =AB /15 so AB = 45/underoot 13

So perimeter = 2(AB+ BC)

                  = 2(30/underoot 13  + 45/underoot 13)

                  = cc
