The measure of a central angle is 3 x + 18, and the measure of its arc is 147°. which equation can you use to find the value of x ? 2(3 x + 18) = 147° 3 x + 18 = 2(147°) 3 x + 18 = 147°

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
