Answer:
sum of angles at a point is equal to 360
so, 360= 163+ x°+ y°+z°
y°=360-163 -x° - z°
y°=197- x° -z°
Hello!
It is False because t is multiplied by a negative number, so to solve for it you will need to divide both sides by -3 which mean you have to flip the sign.
Hope this helps!
11-2×48= 412. So the value of the expression is 412.
