I don't know if my answer is completely correct, but I think it's 100. All triangles add up to 180, and an isosceles triangle has 2 equal sides. 40 would be the 2 sides, and 180 subtracted from 80 equals 100.

b
Step-by-step explanation:
1/8 is 12.5% so it is bigger than 12%

the side of the square is 18cm
I believe it is 6,895. I just multiplied by 197 by 35
