Answer:
The domain of this function is all real numbers
Step-by-step explanation:
Unless there is a domain restriction for the function, the domain of a function is all real numbers. This means that all we need to do is determine whether there is a domain restriction.
The things that cause a domain restriction are: an x in the denominator of a fraction like or a radical like
As there are no variables in the denominator or a radical, we can conclude that the domain of this function is all real numbers.

Answer:
x = 60
Step-by-step explanation:
the chord- chord angle x is half the sum of the measures of the arcs intercepted by the angle and its vertical angle.
The sum of the arcs in a circle = 360° , then
intercepted arc = 360° - (35 + 25 + 205)° = 360° - 265° = 95°
then
x = (95 + 25 ) =
× 120 = 60
