anonymous · Answer

howd u get that

ipwnbunnies · Answer

It would be nice if we were able to see the whole question.

anonymous · Answer

Marissa wants to hang a string of lights on the front of the canopy, as shown in the drawing below

anonymous · Answer

what is the total length of the string of lights that she will need

ipwnbunnies · Answer

Ahh, gotcha. We needs the Pythagorean Theorem.

anonymous · Answer

ok so it would be 8 squared plus 3 squared = c squared right?

ipwnbunnies · Answer

She wants to hang up lights on that bold triangle there. And as you can see, the big triangle is broken up into 2 congruent right triangles.

ipwnbunnies · Answer

Yes, that would be the best thing to do. :3

anonymous · Answer

i got73

ipwnbunnies · Answer

Oh no, not 8. That would be the length of that whole big triangle.

ipwnbunnies · Answer

As I said, we can break it up into 2 right triangles.

ipwnbunnies · Answer

So, the bottom side of one right triangle will actually be 4.

anonymous · Answer

So whats the next step

ipwnbunnies · Answer

Use the Pythagorean Theorem on one of the smaller right triangles. The height will still be 3, but the base has a length of 4.

anonymous · Answer

so i would have to do 3squared plus 4squared....?

ipwnbunnies · Answer

Yes ma'am. We want to get the length of that hypotenuse. The lady wants to put lights there. :3

anonymous · Answer

Ok hold on

anonymous · Answer

ok  got 5

ipwnbunnies · Answer

Right. So, that diagonal will have a length of 5 feet. As you see, there are like 2 lines on both of the diagonals. That means they are congruent.
So the other diagonal will also be 5 feet.

anonymous · Answer

OH so the answer is 10 ok i got it

anonymous · Answer

thank u

ipwnbunnies · Answer

No, the answer isn't 10 .-.

anonymous · Answer

oh its not dang it

ipwnbunnies · Answer

She wants to put lights on that big, thick-lined triangle.
That includes the 2 diagonals, plus the bottom of the big triangle. You see now?

anonymous · Answer

yea

anonymous · Answer

is it 13.

anonymous · Answer

u there :/

ipwnbunnies · Answer

No, it's not 13. We have 5 feet on the one diagonal you found. Since the other one is congruent, it will also be 5 feet. Then, the third side of our triangle is complete with the 8 foot base. 
That's the triangle she's trying to get the lights on.

anonymous · Answer

oh its 18 geez im dumb ok thaks

ipwnbunnies · Answer

No prob.
