Area = 1/2 b h b : base h : height The height is vertical side of the right angle; the base is the horizontal side of the right angle
You have to use trig. If the base angle is a and base b, the height is b tan(a).
Assuming you know the angle of ascension, and the base, you can calculate the height by recalling that tangent theta is height over base. Simple algebra from there: height is tangent theta times base.
the equation is 1/2 x base x height or (base x height)/2
i dont care about math even though i use it.
(base x height) / 2
Let the angle = θLet the height = aLet the base = b* means multiplied byIf the angle touches the base:tanθ = a/bb = a/tanθIf the angle touches the height:tanθ = b/ab = a*tanθWhen transferring the second line of working (b= ...) into a calculator, replace a with the height and θ with the angle. The answer will be b.
consider a right angle triangle ABC with AB is the base BC is the height , assume that BC is the height of the hillfind the length ABfind the angle BACuse the above equationBC= (tan BAC) * ABso BC is the height of the hill
a right angle is 90o
It is: perimeter minus hypotenus+base = height Area = 0.5*base*height
