Answer:
x = 6
Explanation:
Its not clear from the question but sides 6, 8 and 10 are used quite commonly in mathematics for right triangle.
Taking side 10 as the Hypotenuse, H
And 8 as Perpendicular, P
Base, x will be
H² = P² + x²
10² = 8² + x²
x² = 100 - 64
x² = 36
x = 6
I would say...
-straight
- durable
-layered
