How do I do this I’m really confused

4√6

Step-by-step explanation:

because one of the angles is given to be 90 deg, the triangle is a right triangle. hence we can use the Pythagorean formula to find the 3rd side

(see attached for reference)

let the missing side be x.

We are given the length of the other side is 2 and the hypotenuse is 10

applying the pythagorean formula:

x² + 2² = 10²

x² + 4 = 100

x² = 100 - 4

x² = 96

x = √96

x = √(16 x 6)

x = √16 √6

x = 4√6
