How do you find the altitude of a triangle when you are only given the sides?

Question

It's one step in ten for precalc-I'm not being lazy, I promise.

Answer 1

formula and it depends on what type of triangle

Answer 2

Find an angle usung the law of cosines. The altitude will form a right triangle with a known side as the hypotenuse & you have already found 1 of the other angles. The altitude will be opposite this angle & will equal the hypotenuse times the sine of the angle.

Answer 3

You use sine, cosine and tangent. For example, a right triangle with a hypotenuse of 4 and a leg (the one on the bottom) of 3, has altitude x degrees in which cos x = 3/4.

Answer 4

suppose the sides are a b and c and you want to find the alttitude on a

find the area of the triangle

s = (a+b+c)/2

area = sqrt(s(s-a)(s-b)(s-c) say A

now area

A = 1/2 ah or h = 2 A/a

Answer 5

you figure out the sides add multiply and walah the answer!
