OpenStudy (mertsj):

Do you know the Pythagorean Theorem?

OpenStudy (mertsj):

a^2+b^2=c^2 That will be true if the triangle has a right angle. If it is not true, the triangle does not have a right angle.

OpenStudy (mertsj):

So you have two problems: :\[7^2+24^2=25^2\] \[6^2+20^2=24^2\]

OpenStudy (anonymous):

yeah, and i get this. 576 + 49 + 625(first triangle) 400 + 36 + = 576 (second tirangle)

OpenStudy (mertsj):

Which one is true?

OpenStudy (anonymous):

the first one does have an angle of 90 degree, because the sum of the two legs are equal to the second power are equal to the hypothenuse to the second power. Just as when you apply the theorem and the numbers match.

OpenStudy (mertsj):

sum is singular and you should use a singular verb. Try this: The first drafting triangle is accurate because it has a right angle. We know this because of the Pythagorean Theorem which says, in a right triangle the sum of the squares of the legs is equal to the square of the hypotenuse. 7^2+24^2=25^2 but in the second triangle, 6^2+20^2 is not equal to 24^2

thank you very much, can you help me on another one, this one will be the last one and its the last one of the test. but its really confusing.

OpenStudy (anonymous):

@Mertsj ?

OpenStudy (mertsj):

He can say: The definition of sinx is side opposite angle x/hypotenuse. The side opposite is the distance between the earth and the moon that the scientist is trying to find. He knows the angle x and the hypotenuse which is the distance between the moon and the sun. The equation has only one unknown and can be solved for the side opposite.

OpenStudy (anonymous):

So how can I explain that? please this is my last question i've been doing two exams today and is really stressing :(

OpenStudy (mertsj):

I wrote that explanation. I thought it was a good one. If you don't think so you can modify it to whatever you think is good.

OpenStudy (anonymous):

so is it ok to write it exactly as you put it there? if it is then its all good.

OpenStudy (mertsj):

I thought so.

OpenStudy (anonymous):

ok, ill go for that, thanks. a lot!
