Question

some a triangle in which a b is equal to 7 centimetre angle A is equal to 45 degree and Angle C is equal to 75 degree and Angle b is equal to 180 degree minus bracket 45 degree + 75 degree bracket is equal to 60 degree

Answer 1

yes
<a=45°
∠c=75°
∠b=180-(∠a+∠c)
    =180-(45°+75°)
   =180-120
   =60°
