Use the converse of the Pythagorean theorem to decide whether ΔABC is a right triangle by answering the questions.
navik [9.2K]

Answer:

Pythagorean theorem: a^2 + b^2 = c^2

1. we have to find a. b is 12 and c is 15 because the right angle is pointing towards 15 so that is the hypotenuse. then we simply plug the info in the equation we have above.

a^2 + 12^2 = 15^2

a^2 + 144 = 225

a^2 = 81 --> sqaure root to find the answer basically.

a = 9

- we put AD as a so AD = 9

final answer : 9

2. to find AC, simply add AD and DC.

9 + 16 = 25

final answer: AC = 25

3. ABC is not a right triangle because it does not have a right angle. the smaller triangles do, but that does not mean that ABC is a right triangle.

-- let me know if you need any further explanations.

Can someone please explain to me how to find the interquartile range of something?
Alika [10]
I’ll do an example you have the numbers 1,5,7,2,9 you can tell the median is 7 right? So go from the very left and the median (7) and do the same thing you do to find median. (Id recommend crossing the numbers off as you go if that makes sense! :)
