The value of x or the missing length is 16 units after applying the Pythagoras theorem option (C) is correct.
What is the Pythagoras theorem?
The square of the hypotenuse in a right-angled triangle is equal to the sum of the squares of the other two sides.
It is given that:
A right-angle triangle is shown in the picture with dimensions.
A right-angle triangle is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
It is required to find the value of x.
To find the value of the x we can use Pythagoras theorem:
Using Pythagoras theorem:
hypotenuse² = perpendicular² + base²
Let the red line length is y
(15)² = 9² + (y)²
y = 144 units
x = 144/9
x = 16 units
Thus, the value of x or the missing length is 16 units after applying the Pythagoras theorem option (C) is correct.
