Answer:
8
Step-by-step explanation:
Because it is equal to the 4 side
Use a^2 + b^2 = c^2
the triangle must be isosceles because the two angles are the same
1.2^2 + 1.2^2 = x^2
1.44 + 1.44 = x^2
2.88 = x^2
x=6√2/5
or
x ≈1.69706
You know they are parallel because the lines will never intersect or meet. (Two straight lines usually mean it is parallel)
