Question

105°+45°+110°+x=180°

Answer 1

105°+45°+110°+x = 180°

=> 260°+x = 180°

=> x = 180°-260°

=> x = - 80°

Answer 2

HEYA ❣️

105°+45°+110°+x=180°

260+x=180

x=180-260

x=-80

BUT THESE ARE THE MEASURES OF AN ANGLE, AND WE KNOW THAT ANGLES ARE NEVER BE IN NEGATIVE VALUE. SO, WE CAN SAY THAT ANGLE X IS OF 80°.
