Based on your value of x in question #1, what is the value for ∠EHF
Ludmilka [50]

Answer:

∠EHF = 132°

Step-by-step explanation:

Both angles lie on a straight line.

=====================

  • ∠EHF + ∠FHG = 180°
  • 2(x) + 48° = 180°
  • 2(x) = 180° - 48°
  • 2(x) = 132°
  • x = 66°

Then ∠EHF :

  • 2(x)
  • 2(66)
  • 132°
