Answer:
x = −1.24
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−132.3x=165.1
Step 2: Divide both sides by -132.3.

x= -1.247921
Step-by-step explanation:
the formula is :
tan (a+b) =
(tan (a) + tan (b)) / ( 1 - tan (a) . tan (b))
therefore
tan (π/5) + tan (π/2)) / (1-tan (π/5) tan (π/2))
= tan (π/5 + π/2)
