Please solve me this question with steps.

Hey There! This is your solution......................
a) Let the base angles be (x) and (x) respectively.
Then,
x + x + 40 = 180
Or, 2x + 40 = 180
Or, 2x = 180 - 40
Or, 2x = 140
Or, x = 140/2
Or, x = 70
Hence,
The base angles are 70 and 70 respectively.
b) No, A triangle can't have anles as 60,70 & 70.
PLEASE MARK ME BRAINLIEST..................
a) AB = AC
It is an isosceles triangle cause if two sides of the triangle are congruent or equal , then the triangle is isosceles..
So we know that in isosceles triangle the base angles of the congruent sides are equal so
Angle ABC = ACB
Total by angle sum property the total sum of angles of a triangle is 180 degree
ABC + ACB + CAB = 180
x + x + 40 = 180
2x + 40 = 180
2x = 180 - 40
2x = 140
x = 140/2=70
So both the angles have 70 degrees
b) No it can't have those angles as their sum will not be equal to 180 degrees so it will violates thr angle sum property of the triangle
