Question

In ΔABC, ∠A =54 ° , ∠B = 40 ° then ∠C =​

Answer 1

Answer:

angle c is 86 degree

Step-by-step explanation:

because , the sum of measure of three angle should be 180 degree

40+54+86is 180

Answer 2

Answer:

86°

Step-by-step explanation:

∠A = 54°

∠B = 40°

∠C = x

∠A+∠B+∠C = 180°

54°+40°+x = 180°

94° + x = 180°

x = 180° - 94°

x = 86°

∠C = 86°
