Answer:

Step-by-step explanation:

Sum of all the angles of a triangle = 180°

∠A + ∠B + ∠C = 180°

48 + ∠B + 56 = 180

∠B  + 104 = 180

∠B = 180 - 104

∠B  = 76°

Answer:

76

Step-by-step explanation:

if you mean find angle b

then you do 48 + 56 to get 104

then take 104 from 180 to get 76

and b is 76 degrees

hope this helps :)
