It says Find the Value of X I have no idea how to solve it please help.

PRQ is an inscribed angle in a circle......its measure = 1/2 of the measure of its intercepted arc

So x = (1/2) (154) = 77°

1/2 * 154 = 77 degrees

I hope I am right

Correct, ND !!!!!

Just like what Chris said, PQR is an inscribed angle, and by definition, an inscribed angle is equal to 1/2 the measure of the arc it contains.

Therefore, 1/2 * 154 is 77, just like NaturalDisaster and CPhill had said.
