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
