Find the value of x and y in each figures (ii)​

Answer»

HERE IS UR ANSWER DEAR,

in the triangle ,WHOSE ANGLES were

  • 90°
  • ×°
  • 30°

by taking that triangle ,

sum of all the angles in a triangle = 180°

x°+90°+30° = 180°.

x + 120° = 180°.

x= 180° - 120°

x= 60°

then in the triangle whose angles were

sum of the angles in triangle= 180°

A°+20°+60° =180°

A° +80° = 180°

A°= 180°-80°

A°=100°

and

the angles that are adjacent in a straight base side were

  • A°=100°
  • y°

sum of the adjacent angles= 180°

100°+ y° = 180°

y° = 180° -100°

y° =80°

therefore ,

  • x°=60°
  • y°=80°
