Question

In order to do pathygreom therom how do i know which is A,B,C of the triangle...?

Answer 1

the diagram tells you; or the problem tells you

Answer 2

dont get hung up on the 'names' of the variables; just know what the pythag meas

Answer 3

The shortest side is A, the side perpendicular to that is B, and the diagonal is C.

Answer 4

leg^2 + leg^2 = hyp^2

Answer 5

Here is the problem... maybe this whill help out with my question a little

Answer 6

this is the application of the law of cosines

Answer 7

But dont i need to find out the other side in order to do law of cosines..?

Answer 8

ohh nevermind your right!!!! :]]
thankss

Answer 9

the third side is:

3rd side = \(\sqrt{6^2+10^2 -(2*6*10*cos(80))}\)

Answer 10

once you have that sides; you can law of sine it to ge the angles

Answer 11

thats the c^2=a^2*b^2-2(a)(c)cos80 yea :] but couldnt i use pathygreom therom for this ...

Answer 12

well, that IS the pythag thrm, or better; the pythag thrm is the law of cosines when the angle = 90

Answer 13

what happen when cos(90) is used in the law of cosines?

Answer 14

since you only know one angle, and it aint 90; pythag aint gonna help you out is it

Answer 15

ohh well i guess that explains it alot i just use it all the time no matter what the circumstance is if i only have two angles i usually just do pathagreom theroem though im always wrong i never know why youve been much help as always to me thank you !
