Question

Someone please help me with this

Answer 1

Since 2 sides of the triangle are the same, it's an isosceles triangle.
That would also mean that the two angles are the same; 70 and 70.

A triangle has 180 degrees total.

70 + 70 + x = 180
x = 40

Answer 2

I would say either 40 or connot be determined.
because that is the most lgical conclusion.
