Mr. Kelly wants to hang “icicle” Christmas lights and wants them to cover exactly from his roof to the top of his window. He really doesn’t want to get up on a ladder to measure so he decides to use some trigonometry. He walks 25 feet away from his house and measures the angle to the top of the window to be 59°. He then measures the angle to the roof to be 66°. How far will the “icicles” be?

≈ 31.657 ft

Step-by-step explanation:

I'm not sure if I interpreted this problem correctly, but:

We are given an AAS triangle, so we should use the Law of Cosines:

Looking at the problem, I believe that it should be set up like this:

Which we can solve for y:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
