What is the arc measure of AC on circle P in degrees?

Given:

∠APE and ∠EPD are congruent.

To find:

The measure of arc AC.

Solution:

Complete angle of a circle = 360°

m∠APE + m∠EPD + m∠DPC + m∠CPB + m∠BPA = 360°

m∠APE + m∠APE + 42° + 74° + 136° = 360°

2 m∠APE + 252° = 360°

Subtract 252° from both sides.

2 m∠APE + 252° - 252° = 360° - 252°

2 m∠APE = 108°

Divide by 2 on both sides.

m∠APE = 54°

Given ∠APE and ∠EPD are congruent.

m∠EPD = 54°

m∠APC = 54° + 54° + 42°

             = 150°

The measure of central angle is congruent to the measure of the intercepted arc.

m(ar AC) = m∠APC

m(ar AC) = 150°

The arc measure of AC on circle P is 150°.

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

answer: y=0 if that is what u r looking for
