Question

Find the length of the third side to the nearest tenth.

Answer 1

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
