Answer 2

(d) 10.63

Explanation:

You want the length of the hypotenuse of a right triangle with legs 7 in and 8 in.

Pythagorean theorem

The Pythagorean theorem tell you the relationship between legs a, b, and hypotenuse c of a right triangle is ...

c² = a² +b²

Application

In this figure, this means ...

x² = 7² +8² = 49 +64 = 113

x = √113 ≈ 10.63

The length of x is about 10.63.
