Angle y° and (5z - 44)° are linear pairs, meaning that the two measures together will add up to 180°. To solve for z, know that (5z - 44)° and 76° are vertical angles, meaning that both angles are the same. So simply set them equal to each other to find z: 5z - 44 = 76 5z = 76 + 44 5z = 120 z = 24
Now to solve for y, remember that since (5z - 44)° and 76° are vertical angles, they are the same, meaning you can denote (5z - 44)° as simply 76°. Like I said earlier, y and 76° are a linear pair so simply subtract 76 from 180 to find y: 180 - 76 = 104°
