Answer: 8.9 and 6.7
Explanation:
These are right triangles, so you can use the Pythagorean theorem, a² + b² = c², where a and b are the legs, or shorter sides, of the triangle and c is the hypotenuse, or the longest side.
1. 4² + 8² = c²
16 + 64 = c²
80 = c²
c = √80
c = 8.9
2. 6² + 3² = c²
36 + 9 = c²
45 = c²
c = √45
c = 6.7
