Question

not the upper one say answer of the middle one​

Answer 1

Answer:

Let Angle 1 be a , Angle2 be b and angle3 be c .

Now we know that a = b

and c = a + 30.

Now, we know that the sum of all the angles of a triangle is equal to 180.

So, a+b+c= 180

So we can substitute b for a and c for a +30.

Now, a+a+(a+30)= 180.

= 3a+30=180

= 3a= 180-30

=3a=150

=a = 150/3

= a = 50
