Q:
# If cos(x) = 0.5, then what is x?

Accepted Solution

A:

Answer:=60 the second option.Step-by-step explanation:Given the trigonometric ratio, we can find the value of the angle by simply finding the inverse of the given ratio.If for example Cos ∅= a, then ∅=Cos⁻¹a If Cos (x)= 0.5, then x= Cos⁻¹ 0.5Cos⁻1 0.5=60°The angle whose sine is 0.5 is ∅=60°
