You use the circumference formula to find the circumference of the tire. Multiply it by 18 Bc it revolves 18x. Then since it was in inches they ask for feet instead so divide the answer by 12 to get your answer. Mine is the exact answer and the question asks for rounding it to the nearest hundredth, just use calculator or replace the pi as 3.14

Can anyone help ? i really don’t understand this question <br> If NP bisects X =<br> m/RNM =
snow_tiger [21]

We can conclude that the value of x is (∠MNP + 66)/8 and angle m∠RNM = ∠RNQ - ∠MNP + 78.

<h3>What are angles?</h3>
  • An angle is a figure in Euclidean geometry formed by two rays, called the sides of the angle, that share a common endpoint, called the vertex of the angle.
  • Angles formed by two rays are located in the plane containing the rays.
  • Angles are also formed when two planes intersect.
  • These are known as dihedral angles.

So,

  • ∠MNQ = ∠MNP + ∠PNQ
  • 8x + 12 = ∠MNP + 78
  • 8x + 12 - 78 = ∠MNP
  • 8x - 66 = ∠MNP
  • 8x = ∠MNP + 66
  • x = (∠MNP + 66)/8

Now, substitute 'x = (∠MNP + 66)/8' in 8x + 12:

  • ∠MNQ = 8x + 12
  • ∠MNQ = 8 ×(∠MNP + 66)/8 + 12
  • ∠MNQ = ∠MNP + 66 + 12
  • ∠MNQ = ∠MNP + 78

Hence, m∠RNM = ∠RNQ - ∠MNP + 78

Therefore, in the given question value of x is (∠MNP + 66)/8 and angle m∠RNM = ∠RNQ - ∠MNP + 78.
