Question

If the measure of an intercepted arc is 118°, and the measure of the inscribed angle is 2x - 1, what is the equation to find the value of x?

2x - 1 = 118°
2(2x - 1) = 118°
2x - 1 = 2(118°)

Answer 1

measure of the arc is = to the angle. like nikato said before.

Answer 2

ok

Answer 3

so which do you think it is?

Answer 4

No, this is different. Since this is an inscribed angle, the measure of the angle is actually half the measure of its intercepted arc

Answer 5

gosh. i dont read instructions well today.

Answer 6

2 (2x - 1) = 118
