From given figure, sinx+secx+tanx is α, find 156α.
For the angle x in a right angled △,
sinx=OppositeHypotenuse,
secx=HypotenuseOpposite and
tanx=OppositeAdjacent
From this △, we get
So, sinx=513, secx=1312 and tanx=512
Using above values in given expression,
⇒sinx+secx+tanx=513+1312+512
⇒α=294156
⇒156α=294
