Darnell is trying to understand the Pythagorean Theorem by drawing a few triangles. He found that 1² + 1² = (√2)² is accurate. W
Sergeeva-Olga [200]

Answer:

D. The triangle is a right triangle, the lengths of its sides are 1 and 1 with a hypotenuse of √2.

Step-by-step explanation:

The Pythagorean Theorem is modeled by a² + b² = c².

c represents the hypotenuse and a and b represent the other two sides.

The Pythagorean Theorem can only be applied to right triangles.

What is the ratio of the perimeter of ΔHKO to the perimeter of ΔFGO
slamgirl [31]

I think you meant to say the ratio of the areas (not perimeters). Also, HKO and FGO are not showing up, so it seems like a different problem. I'm going to answer the question you posted in the image attachments.

The triangle ABC has area 12 since

A = b*h/2 = 4*6/2 = 24/2 = 12

Triangle CEF has area 48 because

A = b*h/2 = 8*12/2 = 96/2 = 48

The ratio of the areas is found by dividing the area of ABC over the area of CEF (as the last box instructs) so we have 12/48 = 1/4

Therefore, the area of ABC is 1/4 that of the area of CEF

----------------------

In summary,

<h3>Answer for the first box: 12</h3><h3>Answer for the second box: 48</h3><h3>Answer for the third box: 1/4</h3>

8. Persevere The perimeter of another quilt had to be 34 feet because he only had that much binding. he wanted it to be 8 feet l
valentinak56 [21]
So, 34 divided by 8 is 4.25 so thats the missing side length. It gives you the other one which is 8. So 4.25 times 8 would be your area. 4.25*8=34. your answer is 34 feet squared.
