<h3>
Answer: 2pi</h3>
2pi radians are equal to 360 degrees. After this point, the function f(x) = sin(x) repeats its values again. Each cycle is 2pi radians long.
The value of x = -3/2 .
<h3>What is an Equation ?</h3>
An equation is a mathematical statement that relates unknown variable to constants to determine their value.
The equation given is
(2x+3 ) / 7 Divided by 1 = 0
2x +3 = 0
2x = -3
x = -3/2
Therefore the value of x = -3/2 .
The complete equation is
(2x+3)/7

Answer:
34°
Step-by-step explanation:
The measure of vertical angles formed by two chords is equal to one half the sum the measures of the arcs.
In other words, x is the average:
x = (23° + 45°) / 2
x = 34°
