Answer:
The answer to your question is b = 9.5
Explanation:
Data
hypotenuse = 10
leg 1 = 3
Process
1.- To solve this problem use the Pythagorean theorem.
c² = a² + b²
c = hypotenuse = 10
a = 3
b = x
2.- Solve for b
b² = c² - a²
3.- Substitution
b² = 10² - 3²
4.- Simplification
b² = 100 - 9
b² = 91
5.- Result
b = 9.5
