Please help me with this problem and explain how to solve these

Option A:

The simplest radical form of x is .

Solution:

Hypotenuse = 16 in

Two sides are 11 in and x.

To find the value of x:

Pythagoras theorem:

In a right angle triangle, the hypotenuse is equal to the sum of the other two sides.

Subtract 121 from both sides of the equation.

Taking square root on both sides of the equation.

Hence option A is the correct answer.

Hence the simplest radical form of x is .

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
