A right triangle and two of its side lengths are shown in the diagram. 39 cm
12 cm
x cm
Which measurement is closest to the value of x in centimeters?

B. 1.9 mi

Explanation:

The shortest distance from Natasha's house to the library = hypotenuse of the triangle = x

Since the triangle is a right triangle, we can find x by applying Pythagorean Theorem.

Thus:

x² = 1.7² + 0.9²

x² = 2.89 + 0.81

x² = 3.7

√x² = √3.7

x ≈ 1.9 mi
