The value of the side length x is 0

How to determine the side x?

The triangle is a right triangle.

So, we can make use of the following equations:

  • sin(45) = opposite/hypotenuse
  • cos(45) = adjacent/hypotenuse
  • tan(45) = opposite/adjacent

Using the tangent expression, we have:

tan(45) = 9/x

Evaluate tan(45)

1 = 9/x

Cross multiply

x = 9

Hence, the value of the side length x is 0
