Question 156672
You would have to know the height of the building and the proximity of the fire to the building.  Then to find the angle, you would have to do the inverse tangent function.  You do that by taking your calculator and pushing the "2nd" button, then the "TAN" button.  Then enter in the value or fraction for [(how far the fire is from the building)/(the height of the building)], in other words, the opposite over the adjacent of this angle.  Close the parentheses and press "ENTER".  The value you get is the measure of the angle.


I hope this helped!
