Answer: 8.7 m

Step-by-step explanation:

This is a right angled triangle question.

a^2 + b^2 = c^2

a^2 + 5^2 = 10^2

a^2 + 25 = 100

a^2 = 100-25 = 75

a = √75 = 8.7

Answer:

8.7

Step-by-step explanation:

Using the Pythagorean Theorem (a^2 + b^2 = c^2), we get:

a^2 + 5^2 = 10^2

a^2 = 10^2 - 5^2

= 100 - 25

a^2 = 75

Taking square roots on both sides of the equation, we get:

a = 8.7
