Ireally need slmeoner to do this is have no idea how, do all and show work or as many questions as u can. will mark
show work

It looks like you are good up to problem 4 so I will start there. I believe this is practice worksheet featuring the pyth. theorem. The pyth. theorem is used to find the length of sides in a right triangle notable the hypotenuse (side opposite of 90 degree angle).

4. The monitor is a rectangle but that does not stop you from constructing a right triangle. The smaller lengths are 16 in and 12 in respectively. The hypotenuse of the triangle is the diagonal of the rectangle. To find the length use the pyth. theorem.

diagonal^2 = 16^2+12^2

diagonal = 20 in

7. You know the speeds of both trains and the time spend traveling. You know they are traveling at a 90 degree angle so you can use pyth. theorem. But wait... you need to find the distances traveled for both trains. You can find that though because speed x time = distance.

50mph x 3hrs = 150mi

40mph x 3hrs = 120mi

The distance between the trains after 3 hours is the hypotenuse which can be determined by pyth. theorem.

distance^2 = 150^2+120^2

distance = 192 mi approx.

8. First find length of one piece of wiring. Use pyth theorem. Actually 3,4,5 pyth. triplet in which 5 is the hypotenuse. So you have 5 ft for the length of one piece of wiring. How many pieces of wiring do you need? Well, each tree needs 3 pieces and there are 6 trees so you need 18 pieces.

18 x 5 = 90 ft of wiring

From the work I see, you have a great understanding of the pyth. theorem. Keep it up!

alright well the answers to your question is
