How to solve trig equations for exact values
Web- You are solving for the HYPOTENUSE. Therefore you need the trig function that contains both the OPPOSITE and the HYPOTENUSE, which would be SINE, since sin = OPPOSITE / HYPOTENUSE. "Let's input the value into the equation." sin (deg) = … WebSay you are standing at the end of a building's shadow and you want to know the height of the building. you only know the length (40ft) of its shadow and the angle (say 35 degrees) from you to its roof. you could use the tangent trig function (tan35 degrees = b/40ft) 40ft * tan35 = b 28ft = b
