Answer:
A) 7.8
Explanation:
The side lengths of the triangle are 5 units and 6 units.
Using the Pythagorean Theorem, a²+b²=c², we can find the hypotenuse, c, given side lengths a and b:
a²+b²=c²
5²+6²=c²
25+36=c²
61=c²
√61=c
7.81≈c
Therefore, the hypotenuse is about 7.81 units, making A the closest choice.
