Math Problem Statement

Given m || n, find the value of x and y.

Solution

To solve for xx and yy, we first use the fact that mnm \parallel n. In parallel lines cut by a transversal, corresponding, alternate interior, or supplementary angles are related.

Observations:

  1. Angle Relationships:
    • The angle 6x166x - 16° is a vertical angle to 3x+173x + 17°, so they are equal:
      6x16=3x+176x - 16 = 3x + 17

    • The angle 2y+142y + 14° and 6x166x - 16° are consecutive interior angles (or supplementary), so: (6x16)+(2y+14)=180(6x - 16) + (2y + 14) = 180

Step 1: Solve for xx

From the vertical angle equation: 6x16=3x+176x - 16 = 3x + 17 Simplify: 6x3x=17+166x - 3x = 17 + 16 3x=333x = 33 x=11x = 11

Step 2: Solve for yy

Substitute x=11x = 11 into the supplementary angle equation: (6x16)+(2y+14)=180(6x - 16) + (2y + 14) = 180 Substitute 6x166x - 16: (6(11)16)+(2y+14)=180(6(11) - 16) + (2y + 14) = 180 (6616)+(2y+14)=180(66 - 16) + (2y + 14) = 180 50+2y+14=18050 + 2y + 14 = 180 2y+64=1802y + 64 = 180 2y=1162y = 116 y=58y = 58

Final Solution:

x=11,y=58x = 11, \quad y = 58
