Question

Find the missing side of the triangle.

Answer 1

Answer: B.
`2√(26)`

Explanation:

We can use the Pythagorean theorem where a and b are the legs and c is the hypotenuse. Then we will solve by squaring, reverse operations and isolating the variable x.

a² + b² = c²

11² + x² = 15²

121 + x² = 225

x² = 104

x =
`√(104)`

x =
`√(4*26)`

x =
`2√(26)`

This leads us to the answer of;

B.
`2√(26)`
