Answer:
13.2 cm
Step-by-step explanation:
b = ![\sqrt{c^{2} - a\\^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7Bc%5E%7B2%7D%20%20-%20a%5C%5C%5E%7B2%7D%20%7D)
b = ![\sqrt{20^{2} - 15\\^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B20%5E%7B2%7D%20%20-%2015%5C%5C%5E%7B2%7D%20%7D)
b = ![\sqrt{400-225\\} \\](https://tex.z-dn.net/?f=%5Csqrt%7B400-225%5C%5C%7D%20%5C%5C)
b = ![\sqrt{175}](https://tex.z-dn.net/?f=%5Csqrt%7B175%7D)
b = 13.228
b= 13.2 cm
:) good luck on the rest!
A² + b² = c²
15² + b² = 20²
b² = 20² - 15²
b² = 175
b = √175
b = 13.2 (Rounded to the nearest tenth)
