Question

From the figure Show that x+y90°

Answer 1

HEYA MATE, HERE IS UR ANSWER

$<b><i>Using sum angle property of the triangle$

angle A+ B+C=180

x+(x+y)+y=180

x+x+y+y=180

2x+2y=180

Taking 2 common

2 (x+y)=180

x+y=180/2

x+y=90

Hence Proved

Answer 2

angle A+ B+C=180

x+(x+y)+y=180

x+x+y+y=180

2x+2y=180

Taking 2 common

2 (x+y)=180

x+y=180/2

x+y=90

Hence it is Proved.
