You need to find the unknown base. Draw a right triangle, with the vertical height "h". By trigonometry, half the base, divided by "h", is equal to tan(alpha/2), where "alpha" is the angle. Therefore, the base "b" is equal to 2*h*tan(alpha/2), and the Excel formula for the area, (1/2)bh, is 0.5*2*h*tan(alpha/2)*h, which can be simplified to:h^2*tan(alpha/2)

Note 1: You must replace "h" and "alpha" with the correct values, or references to the cells that contain those values.

Note 2: Excel assumes that all angles are in radians. If the angles are in degrees, replace alpha with radians(alpha), to convert the angle.

we can calculate it by the formula C X @ (ALPHA)

go and get a website that tells you the alpha alphebet

the only ones i know are A = alpha C= Charlie D=delta H=holiday R = Romeo J= Juiliet.

Yes. If c is the length of the hypotenuse, and alpha is the angle between the hypotenuse and the base. If we say a is the length of the side opposite angle alpha and b is the length of the adjacent side, then the lengths a and b are as follows:

a=h*sin(alpha)

b=h*cos(alpha)

If you mean what word represents the letter H in the NATO phonetic alphabet then the answer is Hotel. The letter A is represented by alpha, B by bravo and so on.
