The angle ∠HFW is 43° and ∠WFA is 137°.

Step-by-step explanation:

  • When two lines intersect at a point, the opposite angles formed are equal to each other.

(4x-1)° = (3x+10)°

4x-3x = 10+1

x = 11

To find ∠HFW and ∠WFA,

∠HFW = 4x-1

⇒ 4(11) - 1

⇒ 44 - 1

⇒ ∠HFW = 43°

∠WFA = 180° - 43°

⇒ ∠WFA =  137°
