Question

in triangle ABC BC=AB and angle B=70degree. Then angle A is equal to?​

Answer 1

Answer:

a=55

Step-by-step explanation:

we know that the sum of interior angle equal to 180 degrees so 70 minus 180 equal to 110 so divide by 2

So, we get 55 degrees on both angles

Answer 2

Answer:

Angle A = 55 degree

Step-by-step explanation:

Let the angle a and c be x

So, 2x +70 degree =180 [ asp]

So 2x = 180 - 70

=110

X= 110/2

=55 degree
