Answer:

answer is 17.5

Step-by-step explanation:

use formula a^2 + b^2 = c^2 (letters represent each side of the triangle)

9^2 + 15^2 = 306

306 = x^2. find the square root of 306 to find x

√306 = 17.4928557

rounded it to the nearest 10th

17.5

Answer:

X = 17.5

Step-by-step explanation:

X = ?

Hypotenuse² = Base² + Altitude²

x² = 9² + 15²

x² = 81 + 225

x² = 306

X = √306

X = 17.49

X = 17.5
