Answer 1

The answer is D: (5.7cm)

just did the quiz on Edg

Answer 2

Let x be the length of each of two congruent sides.

The triangle will be аcute if:
x² + x² > 8²
2x² > 64
x² > 32
x > √32
x > 5.657

So, the smallest possible length of one of two congruent sides have to be 5.7 cm (to the nearest tenth)
