Angle A is equal to 50 Angle B is equal to 90 because that's a linear pair...and sum of that two angles is 180...so.angle B is 90 And angleC is 40 And sum of all angles in a triangle is 180 So Let us assume angle A is x So... x+90+40=180 x+130=180 x=180-130 x=50 So...angle A =50

And angleC is 40
And sum of all angles in a triangle is 180
So
Let us assume angle A is x
So...
x+90+40=180
x+130=180
x=180-130
x=50
So...angle A =50
