Question

The adjoining diagram shows two intersection straight lines. Find the values of x, y and z

Answer 1

$\sf\red{Given:-}$

$\sf\rightarrow 2x+15°=3x-10°$

$\sf\rightarrow 3x-2x = 15° - 10°$

$\sf \longrightarrow\fbox\red{25°}$

$\sf\rightarrow x+y= 180° [Linear \: pair]$

$\sf\rightarrow 25+y=180°$

$\sf\rightarrow y = 180-25°$

$\sf\rightarrow \fbox\red{y=155}$

$\sf\therefore y=z=155 [vertically \: opposite \: angle]$
