Calculate the height of the building

Tangent of ° =

Height of building

---

Shadow distance

---

If the Height and Shadow distance are given: Angle can be calculated using arcTan
if NaN or infinity appears in the answer box it is normal because the calculation is done automatically as soon as you enter data in one of the input box. Continue entering the data in the second input text box and the NaN or infinity will be replaced by the answer.

Angle is ° =

Height of building

---

Shadow distance

Formula Recall:

Tangent of angle = opposite side of angle divided by the adjacent side of angle.

Angle = arcTan of opposite side divided by the adjacent side
