Right triangle ABC with base of x. (x is between A & B). Hight of Y and hypotenuse Z. The angle between base and hypotenuse is R.

question: If the length of AB is X, what is area of triangle ABC in terms of X and angle R?

Thank you.

Thank you.

Y = XtanR
Area = 1/2 XY = 1/2 X^2tanR

Y = XtanR
Area = 1/2 XY = 1/2 X^2tanR

It's 1/2 (X^2)tanR.
