Question

please help finding the value of x

Answer 1

Step-by-step explanation:

$\sf \huge \underline{ \red{AnSwEr }}:-$

sum property of triangle]

(1) Also each angle of a regular pentagon is 108°

 Hence ∠a + ∠x = 108° 

⇒ ∠x = 108° – ∠a ∴ Equation (1) b

∠b + ∠c + 108° – ∠a  = 180°

⇒ ∠b + ∠c – ∠a  = 180° – 108° = 72°
