HOW DO YOU FIND THE HEIGHT OF A TRIANGLE??????!
I am taking my SAT tomorrow morning, and i am freaking out because i haven't taken geometry for 5 years and i can't even remember how to find the height of a simple triangle! You have no idea how stressed out i am right now! *hyperventilates
Please help me!

It all depends on what is given.
If the base and the area are given, then you can solve for h in
Area=base*height
If the three sides of a triangle are given, you would have to calculate the area of the triangle first using
s=(a+b+c)/2
Area=sqrt(s(sa)(sb)(sc))
If angles and sides are given, you'd have to solve for the triangle using sine rule, cosine rule, or other trigonometric formulae.
Good luck on your exam.
