Answer 14

@ malehuman01
You have a new helper. Good for you. Too many cooks tend to confuse the student.

Answer 15

2?

Answer 16

I thought that tip would help you @Mertsj

Answer 17

I can take all the help I can get it..

Answer 18

The small triangle on the right is a right triangle it obeys pythagorean. There fore you know that the m<e +m<f = 90 degrees do you agree?

Answer 19

I understand it's a right triangle but what do you mean with what follows up?

Answer 20

The triangle on the left is not a right triangle because the long side is 384 for it to be a right triangle it needs to be 388, this means that the angle opposite is less than 90 which means m<B + m<C will be greater than 90, as there is only 180 degrees in a triangle.

Answer 21

Thank you so much radar, I honestly really appreciate the help. But quick question, why must the right triangle have to be 388?

Answer 22

For it to be a right triangle the long side squared must equal to the sum of the square of each leg. Other words 18^2 + 8^2 that means it must be 388 .......not 384!

Answer 23

makes sense, thank you!

Answer 24

You're welcome, \[2\sqrt{96}=384\]
