Answer:
c
Step-by-step explanation:
It’s an isosceles triangle, so both the legs will be congruent, and then we can use the Pythagorean thrm
8^2+8^2=x^2
64+64=x^2
128=x^2 *square root both sides*
x=11.3
So the answer would be C

In all triangles, inner angles add to 180 degrees.
In an isosceles triangle, the base angles are the same and the vertex angle is different from the rest.
b= (180-40)/2
b= 140/2
b=70
Final answer: 70 degrees
