what is the value of x? 20, 30, 41, 56, 61

Answer 1

Answer:

x = 41

Step-by-step explanation:

$\because \angle 1 \:\&\: \angle 2 \: are \: supplementary\\

\therefore \angle 1 + \angle 2= 180°\\

\therefore 3x°+ (2x-25)°= 180°\\

\therefore 5x°-25°= 180°\\

\therefore 5x°= 180°+ 25°\\

\therefore 5x°= 205°\\

\therefore x = \frac{205}{5}\\

\huge \purple{\boxed {\therefore x = 41}}$
