Answer:

  • x = 27°

Step-by-step explanation:

Consider the triangle XYW.

Since ∠X is right angle, the other two angles are complementary:

  • m∠Y + m∠W = 90°

Also, VWX and ZYX are straight angles, which are equal to 180°.

According to angle addition postulate we have:

  • m∠Y = 180° - 4x and
  • m∠W = 180° - 6x

Add up the above two and compare with first sum, then solve for x:

  • m∠Y + m∠W = 90°
  • 180° - 4x + 180° - 6x = 90°
  • 360° - 10x = 90°
  • 10x = 270°
  • x = 27°
