Using SIN and COS in a formula

[Rudy Pieterse]

I did math but it eludes me now so many years after school.

In excel in need to work out a formula for calculating the height of piles without a dumpi level or any survey equipment but a tape measure.

I have 2 sides and a right angle to work out the 3rd side.
I can use the adjacent and hypotenuse sides and a right angle (to get the height or opposite side)

Any clever math bofs have a simple formula for me?

Many Thanks,

Rudy

if you've 2 sides and a right angle use pythagoras theorem to get the 3rd

Correct, just needed my memory jogged. Thank you.

a²=b²+c²
