The missing value of x of the right angle triangle with the given circle is gotten to be; 6.5
What is the hypotenuse?
Hypotenuse is the longest side of a right angle triangle.
Now, from the image attached, we see that the missing value x represents the hypotenuse of the right angle triangle formed from the tangent of 6 units.
Thus, using pythagoras theorem, we have;
x = √(2.5² + 6²)
x = √42.25
x = 6.5
